I whipped up a small testcase using clang and it seems that LLVM indeed

Is everyone ok with this?
Oh also note: you almost certainly want to make the
traling-block-as-last-arg syntax work before doing the conversion. That
is, make:
vec::each(v) {|e| ... }
parse (and re-print as such) rather than having to write:
vec::each(v, {|e| ... });
The latter requires hard-to-hack indentation in the pretty printer and
trailing }); lexical uglies all over the code. Best to give users a way
to avoid these.
