Hi

parser.cc is a generated file: you should edit the bison file parser.yy

it shouldn't be too hard to implement this feature, I'll try to work on 
this, but I can't promise I'll finish soon ;)

please feel free to ping me by some days.

Also, if anyone would like to give it a try and implement it it would be 
very helpful :)

cheers
