eeef65b505 Change the signature of (for) and (with).
(for) is restored to clojure-like flatness.
 (with) can be used without the nested list if you don't care about the
        name.

   Tests and examples updated.

f6160c755a Much better version of new error messages.
This version is much simpler.

At the point that the exception is raised, we don't have access to
the actual source, just the current expression. but as the
exception percolates up, we can intercept it, add the source and
the re-raise it.

Then at the final point, in the cmdline handler, we can choose to
let the entire traceback print, or just the simpler, direct error
message.

And even with the full traceback, the last bit is nicely formatted
just like the shorter, simpler message.

The error message is colored if clint is installed, but to avoid
yet another dependency, you get monochrome without clint.

I'm sure there is a better way to do the markup, the current method
is kludgy but works.

I wish there was more shared code between HyTypeError and LexException
but they are kind of different in some fundamental ways.

This doesn't work (yet) with runtime errors generated from Python,
like NameError, but I have a method that can catch NameError and turn it
into a more pleasing output.

Finally, there is no obvious way to raise HyTypeError from pure Hy code,
so methods in core/language.hy throw ugly TypeError/ValueError.

62522a5f86 Allow get with multiple arguments
When calling get with more than two arguments, treat the rest as indexes
into the expression from the former. That is, (get foo "bar" "baz")
would translate to foo["bar"]["baz"], and so on.

This fixes #362.

b78be9a594 Jank @olasd's hack, clean up core.
The core shall from now on be only for the core language bits. Macro
 bits shall live in hy.macros and in hy.compiler. This cleans up
 garbage.

1e24dde153 Merge fn and lambda
We actually only generate an ast.Lambda if (lambda) was called, as a lot of code
expect ast.FunctionDefs (most notably with_decorator).

This allows empty lambdas too.

This object allows to coerce statements to an expression, if we need to use
them that way, which, with a lisp, is often.

494bf0e8ad Remove the import-as and import-from builtins
The new and improved (import) can handle all cases import-as and
import-from did, so drop the latter two from the language. To do this,
the import builtin had to be changed a little: if there's a single
import statement to return, return it as-is, otherwise return a list of
imports.

cb20910d93 Remove `pass' from the language.
This also fixes a bug in the pass optimize missing branch where the code is
something like: [stmt, [], stmt]; in such case we want to filter out [], so
if we end up with [] we can optimize it. This fix is needed otherwise (do)
inside (do) are not properly optimized.
