As for the default set of accepted types for various convertors, if we

In theory Argument Clinic could use any syntax it likes. In practice,
under the covers we tease out one or two bits of non-Python syntax, then
run ast.parse over it. Saved us a lot of work.
"s: accept={str,NoneType}" is a legal Python parameter declaration; "s:
accept+={NoneType}" is not. If I could figure out a clean way to hack
in support for += I'll support it. Otherwise you'll be forced to spell
it out.
