That'd be a question for the HPC people; ron, do you miss complex types in 9c?

_Bool is a notational convenience, maybe helping document functions
returning only pass/fail status, or for the isalpha(2) family of
functions.

For the characters in Plan 9's char set, it's unneeded; you can type
the character in as many keystrokes (Alt, X, xxxx).  For characters
outside Unicode's BMP, it's not terribly helpful, since Plan 9 doesn't
understand them at all.

That said, these universal characters aren't hard to implement at all.
 Come semester's end and I'll submit a patch to add them to the lexer.
