I think Google's Go should be included for those who are curious about it. It is said that it's faster than anything and it looks good.
Maybe this feature request is not for gcc but for a whole @"Google's Go" package group...
btw, found this:
GCC Go FE lives so far just on a separate branch, until it is merged into trunk (and Fedora switches to that version) it can't be included in gcc package itself.
It could be packaged separately, but I'm not interested in doing/maintaining that myself.
Very well. Thank you for the attention and for answering.
I will submit this package to the wish list.
