It's still the case that $ is not going to appear in foo$bar
context in a strict conforming application.  I think the problem
you have in mind is that foo$bar leads to surprises if foo or
bar is a macro, just as use of EGAD when <errno.h> is included
can lead to surprises.

Perhaps the best way to implement extended identifier character
sets would be with a non-conforming mode flag to the compiler
to enable such an extension.  I can see serious problems with
use of non-Roman characters in foreign-language contexts.
What did we respond to the Japanese comment about this?
