Yep! This is really something I miss among low-level stuff.

I implemented (repeatedly :-) some functions that handle that, together 
with handling binary numbers (answering to Roberto here), but I find 
them too "hackish", i.e. they work well for my codebase, but other 
people may use their own variation and interoperability becomes a 
nightmare.

I think something so basic should be in the bare language. Probably it 
doesn't even add much weight to the parser. (Not a problem for me now - 
I'm just wearing my old and dusty professional dev hat :-)
