I'd love to see literal nodes in the compilers be intelligent enough to
know what base a literal number was in.  It might be as simple as
maintaining the literal characters that make up a token and printing using
those, perhaps only if the token is a member of a particular set of classes.

And remember this applies to numeric literals in Array and ByteArray
literals too.

Th above approach might also handle this case well, although I wonder about
