It's a little ugly:
[expr _$0_a]
[v _$0_a]
yikes. actually, I'd rather write 'a' and have it mean '$0-a'. However, I
can't put that '$0-' prefix as an attribute of [#expr] because :
1. comma-messages only are sent after the constructor processes the
arguments
2. comma-messages are disabled for [#expr] anyway, using the new
CLASS_NOCOMMA option, because comma already means something in
[#expr] (for the two-argument function support that I have just
added)
And then I'd rather not write things like [#expr -local $0- a-b] because
that's three meanings of "-" in the same box. ;) I mean something like a
commandline switch that would set "$0-" as the prefix of all following
variables.
[expr _$0.a] seems to fail, and of course [expr _$0-a] won't do
what you want.
I suppose only /[_A-Za-z][_A-Za-z0-9]*/ are accepted in symbols, just like
C syntax.
