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
- (Seemingly) accidental placement of a character meant that the backticks weren't picked up and displayed nicely.
- Everywhere you refer to 'Hy', it has a capital 'h'. Here it did not.
Fixed up minor grammar issue in one sentence
Fixed minor inconsistency with Python and Hy code
- Added variable assignment before code example
As part of the Grand Language Cleanup, a few examples in the tutorial
could be simplified:
* The --init-- function of the defclass example does not need an
explicit None anymore.
* The apply example in the Hy<->Python interop section can use a
keyword instead of a string in the last part.
This perhaps closes#971.

Adds a short (require) example, along with a few words on why macros can't be imported.
Closes#966.

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.

defclass now has a new syntax:
(defclass Name [BaseList]
[property value
property value] ;; optional
(defn method [self]
self.property))
Anything after the optional property list (which will be translated to a
setv within the class context) will be added to the class body. This
allows one to have side effects and complex expressions within the class
definition.
As a side effect, defining methods is much more friendly now!
Closes#850.

This code is heavily, *heavily* based off of Guillermo Vaya
(willyfrog)'s work... instead of defining its own keyword arg though, it
uses the "standard" :kwarg type, which is the main difference from
willyfrog's original branch.
Included tests and some documentation in the tutorial.
Also documented "apply" separately as an example of reproducing
*args and **kwargs.
- Inline code is written using ``double backticks``
- Italicized text uses *asterisks* rather than `single backticks`
- Function parameters are italicized rather than written as inline code
- Standardized capitalization of Hy, Lisp(s), and Python.
- Added periods to the end of list items.
- Use inline code blocks for inline code.
- Stripped trailing whitespace.
- Other miscellaneous grammatical changes.
