It is not at all unreasonable for compiler implementations to support $
in identifiers in system functions or other "internal" uses, without it
being usable for other cases.  A compiler could view it as part of its
reserved namespace, like __identifiers.  But once they do that, it's
usually easier to allow it in ordinary code than add extra checking to
detect and diagnose it.

I've seen many assemblers that use $ for different reasons - to indicate
local labels, for register names, for hexadecimal numbers, for comments.
 It's awkward for compilers to accept $ identifiers when working with
such lower-level tools - it means some sort of name mangling.
