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. Hugo
