ed930edefe Allow keyword args in method calls before the obj (#1167)
Unlike Python, Hy allows the programmer to intermingle positional and keyword arguments. This change removes an exception to that rule for method calls, in which the method callee always had to be the first thing after the method. Thus, `(.split :sep "o" "foo")` now compiles to `"foo".split(sep="o")` instead of `HyKeyword("sep").split("o", "foo")`.

a4158c5543 Add tests for the empty keyword
I have some macros for using pandas and NumPy that expect : to be a keyword instead of an ordinary symbol. These tests will ensure that we don't break this unless we want to.

ed8e37da62 Burninate the synonyms true, false, and nil
Per the straw poll in #908, as an alternative to #1147.

Now you must use `True`, `False`, and `None`, as in Python. Or just assign `true` to `True`, etc.; the old synonyms aren't reserved words anymore.

2242097b6b Translate (.a.b.c x) to x.a.b.c(). (#1105)
Translate (.a.b.c x) to x.a.b.c().

This is useful for, e.g., calling the Series.str.lower method in pandas.

14fddbe6c3 Give require the same features as import (#1142)
Give `require` the same features as `import`

You can now do (require foo), (require [foo [a b c]]), (require [foo [*]]), and (require [foo :as bar]). The first and last forms get you macros named foo.a, foo.b, etc. or bar.a, bar.b, etc., respectively. The second form only gets the macros in the list.

Implements #1118 and perhaps partly addresses #277.

N.B. The new meaning of (require foo) will cause all existing code that uses macros to break. Simply replace these forms with (require [foo [*]]) to get your code working again.

There's a bit of a hack involved in the forms (require foo) or (require [foo :as bar]). When you call (foo.a ...) or (bar.a ...), Hy doesn't actually look inside modules. Instead, these (require ...) forms give the macros names that have periods in them, which happens to work fine with the way Hy finds and interprets macro calls.

* Make `require` syntax stricter and add tests

* Update documentation for `require`

* Documentation wording improvements

* Allow :as in `require` name lists

0880610401 Don't sort or deduplicate the items in a HySet
Fixes #1120.

I also added hy.models._wrapper[set] so a macro can return an ordinary set in place of a HySet.

f4afb0ca7e variadic if
The `if` form now supports elif clauses.
It works like `cond` but without the implicit `do`.
The old `if` is now `if*`

variadic lif now supports "ellif" clauses.

Update if-no-waste compiler to use `if*` properly.

(Sometimes one character is all it takes.)

0a942a069f Support one-arity comparison operators too
Comparison operators such as =, !=, <, >, <=, >= should support a
one-arity version too, and return true in those cases (except for !=,
which returns false).

This closes #949.

32f5d5dea7 Drop a set of brackets from with.
This changes with syntax from (with [[x (expr)] (expr)] ...) to (with
[x (expr) (expr)] ...). Should have no ill side effects apart from the
syntax change.

Closes #852.

9f88e07e1d Drop a set of brackets from let.
This changes let to use a flat list of symbol-value pairs instead of a
vector of vectors. One side effect is that (let [[a 1] z]) is not
expressible now, and one will explicitly need to set a nil value for z,
such as: (let [a 1 z nil]).

Closes #713.

26f342d580 Teach apply about symbol mangling
apply now mangles strings and keywords according to the Hy mangling
rules (by using the same function, now imported from
hy.lex.parser). With this change, if the dict passed to apply has
keywords, strings or quoted symbols, they'll get mangled, to turn them
into proper keys.

This only works for the cases where the keys are directly in the apply
params. A previously deffed dict, or key through a variable will not be
mangled.

This closes #219.
