v0.2.0

Changes since the last release:

• Better error handling in #3
• Pool allocator in #4
• Garbage collection in #5

Things left to do:

• No cons pair support. Only simple linked lists of expressions, cdr is always a list.
• Although there is now garbage collection, everything is still being cloned instead of being passed by reference. This should be added after adding cons pair support.
• Add tail-call optimization (see README).
• Add proper closures (see README).

Version 0.1.0

Basic Lisp programming can be done easily. Manual is almost finished.

Things left to do:

• Bad error handling, just prints to stderr.
• No cons pair support. Only simple linked lists of expressions, cdr is always a list.
• Bad memory management; nothing is passed by reference, instead everything is duplicated. No garbage collection. Could use a pool allocator.
• Add tail-call optimization (see README).
• Add proper closures (see README).
