* module/language/ghil.scm (parse-ghil, unparse-ghil): Rework to make the parse format correspond more closely with the object representation, so that I only have to document it once in the manual. The salient change is that no expression is self-quoting, and that variable references should go through `(ref FOO)'. Rename `set!' to `set'. * module/language/ghil/compile-glil.scm: Add a couple of compilers for unquote and unquote-splicing, that just raise an error. This way I can document unquote and unquote-splicing as normal ghil expressions, except that it's the compiler that catches them if they're outside a quasiquote. (codegen): Adapt to change in <glil-asm>. * module/language/ghil/spec.scm (parse): Fix parser typo bug. * module/language/glil.scm (<glil-asm>): Remove useless <glil-vars> structure, which also had a confusing name. Just put the nargs, nrest, nlocs, and nexts in the <glil-asm> directly. (parse-glil, unparse-glil): Serialize `asm' more straightforwardly. * module/language/glil/compile-objcode.scm (<bytespec>): Remove <glil-vars>, as with <glil-asm>. (preprocess, make-meta, codegen, dump-object!): Adapt to change in <glil-asm>.
