Right. And when we distinguish between the two, we are doing name
mangling.

What we need is an agreed-apon way to handle the case where a $ is in
a symbol an NO_DOLLAR_IN_LABEL is defined, ideally that is agreeable to
C++ and Java maintainers. This extension won't break the C++ ABI because
it doesn't affect standard code.
