Changes from Hy 0.9.8
[ Syntax Fixes ]
* Macros are now module-specific, and must be required when used. (KH)
* Added a few more string escapes to the compiler (Thomas Ballinger)
* Keywords are pseudo-callable again, to get the value out of a dict. (PT)
* Empty expression is now the same as an empty vector. (Guillermo Vaya)
[ Language Changes ]
* HyDicts (quoted dicts or internal HST repr) are now lists
that compiled down to dicts by the Compiler later on. (ND)
* Macros can be constants as well. (KH)
* Add eval-when-compile and eval-and-compile (KH)
* Add break and continue to Hy (Morten Linderud)
* Core language libraries added. As example, I've included `take` and
`drop` in this release. More to come (PT)
* Importing a broken module's behavior now matches Python's more
closely. (Morten Linderud)
[ Misc. Fixes ]
* Ensure compiler errors are always "user friendly" (JD)
* Hy REPL quitter repr adjusted to match Hy syntax (Morten Linderud)
* Windows will no longer break due to missing readline (Ralph Moritz)
Changes from Hy 0.9.7
[ Syntax Fixes ]
* Quasi-quoting now exists long with quoting. Macros will also not
expand things in quotes.

* New (defclass) builtin for class definitions (JD)

[ Errata ]
* Paul was an idiot and marked the j-related bug as a JD fix, it was
actually ND. My bad.
Changes from Hy 0.9.6
[ Syntax Fixes ]
* UTF-8 encoded hy symbols are now hy_... rather than __hy_..., it's
silly to prefex them as such. (PT)

more as a symbol. (ND)
* (decorate-with) has been moved to (with-decorate) (JD)
* New (unless) macro (JD)

* new (global) builtin (@eal)
* new lambda-list syntax for function defs, for var-arity, kwargs. (JK)
[ Language Changes ]
* *HUGE* rewrite of the compiler. Massive thanks go to olasd
and jd for making this happen. This solves just an insane number
of bugs. (ND, PT, JD)
* Eval no longer sucks with statements (ND)
* New magic binary flags / mis fixes with the hy intepreter
(WKG + @eigenhombre)
Changes from Hy 0.9.5

* .pyc generation routines now work on Python 3. (Vladimir Gorbunov)
* Allow empty (do) forms (JD)
* The `else' form is now supported in `try' statements. (JD)
* Allow `(raise)', which, like Python, will re-raise
the last Exception. (JD)

* UTF-8 strings will no longer get punycode encoded. (ND)
* bare (yield) is now valid. (PT)

* Add in the missing operators and AugAssign operators. (JD)
* (foreach) now supports the (else) form. (JD)
[ Language Changes ]
=============== WARNING: WARNING: READ ME: READ ME: ===================
From here on out, we will only support "future division" as part of hy.
This is actually quite a pain for us, but it's going to be quite an
amazing feautre.
This also normalizes behavior from Py 2 --> Py 3.
Thank you so much, Konrad Hinsen.
=======================================================================
* (pass) has been removed from the language; it's a wart that comes from
a need to create valid Python syntax without breaking the whitespace
bits. (JD)
* We've moved to a new import style, (import-from) and (import-as) will
be removed before 1.0. (GN)
* Prototypes for quoted forms (PT)
* Prototypes for eval (PT)
* Enhance tracebacks from language breakage coming from the compiler (JD)
* The REPL no longer bails out if the internals break (Konrad Hinsen)
* We now support float and complex numbers. (Konrad Hinsen)
* Keywords (such as :foo) are now valid and loved. (GN)

Changes from Hy 0.9.4
[ Syntax Fixes ]

(with [context-managed-fn] BODY)
[ Language Changes ]
