values resulting from a function call as the last argument.
doc/ref/api-languages.texi: Add a small blurb about Lua.
module/language/lua/compile-tree-il.scm: Function calls now properly
handle multiple values resulting from a function call as the last
argument.
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.
