:$$ is not a suitable alternative. It already means the current process
:ID. It really cannot be messed with. And ${$} is identical to $$ by
:definition.

Well, not quite. First, writing $var as ${var} is the usual and common
way to disambiguate where there is a problem; second, $$ is rarely
used in a regexp pattern. We can easily migrate perl5 scripts by
translating $$ to ${$} throughout. There is no problem here.
