    lua/lexer tweaks
    
    * module/language/lua/lexer.scm: Some tweaks and reindentations. Remove
      the define/init lexer interface; I don't like separating declaration
      and initialization.
    
    * module/language/lua/parser.scm:
    * test-suite/tests/lua-lexer.test: Adapt to lexer interface change.

    remove true? and false?; lua's truthiness and falsehood is guile's.
    
    * module/language/lua/runtime.scm (true?, false?): Remove, now that #nil
      is false.
    
    * module/language/lua/compile-tree-il.scm: Don't emit calls to true? or
      false?.

commit 6242e3bdbd5118ada21cff86787109fdda4dc5b0
Author: No Itisnt <address@hidden>

    add lua language implementation
    
    What is missing:
    
    + Functions: module, getfenv, setfenv, math.modf, table.sort
    
    + Parser: needs to be more flexible
    
    + Compiler: needs more extensive work to properly handle all possible
    cases of variable arguments, multiple returns, and loops
    
    + Language: Variable arguments and unpacking of multiple returns. (For
    example we need to be able to handle something as complex as
    print(unpack({...})), which is easy with Lua's explicit stack but will
    require lots of tree-il gymnastics, or perhaps modifications to better
    allow different calling conventions. (For instance -- how would we
    support Python or Ruby, where keyword arguments are gathered into a
    hashtable and passed as a single argument?)
    
    What is there:
    
    A fair shot at supporting Lua 5.1, not quite a drop-in replacement, but
    not far from that goal either.

    add return/values hack to compile-glil for lua
    
    * module/language/tree-il/compile-glil.scm (*primcall-ops*): Add a hack
      like 'return but for multiple values, for lua.

    rnrs control only depends on (guile)
    
    * module/rnrs/control.scm: Depend only on (guile).

commit 84b67e1971c3d2dc7e7626f556f6c5e548e948fd
Author: Andy Wingo <address@hidden>
Date:   Fri Dec 10 13:02:24 2010 +0100

    fix self-tail-calls for lexical procs with optional, rest, or kwargs
    
    * module/language/tree-il/compile-glil.scm (flatten-lambda): Don't emit
      a self-label, because when we can't match the args for a lexical call,
      we have no space to shuffle args and jump.
      (flatten): Apply the self-tail-call optimization to optional args
      too, but only if the procedure is fix-allocated. If we can't apply the
      optimization, use the normal tail-call sequence.
    
    * test-suite/tests/optargs.test ("lambda* inits"): Add tests.

commit 3b24aee6e3997c144ec2d1d763c9805a2261768f
Author: Andy Wingo <address@hidden>
Date:   Thu Dec 9 21:53:46 2010 +0100

    clarify compile-glil error messages
    
    * module/language/tree-il/compile-glil.scm (vars->bind-list, flatten):
      Make internal self-checking error messages more clear, for
      implementors of other languages.
