* module/Makefile.am (BRAINFUCK_LANG_SOURCES): Compile at the end. Add compile-tree-il.scm. * module/language/brainfuck/compile-tree-il.scm: New compiler, compiles to tree-il instead of scheme. I thought it would be more illustrative, though there are some uncommented bits. * module/language/brainfuck/parse.scm: Modify not to put a header on the scheme representation. After all, we don't put <scheme> before scheme code, do we? :) * module/language/brainfuck/spec.scm: Add tree-il compiler. * module/language/tree-il.scm: Understand (set! (lexical foo) ...). * module/system/base/language.scm: Update license. Actually, updates licenses on all these.
