What you don't think of is that `$$' gives the PID and what you don't
know is that for special parameter names such as `$' the rest is
ignored.
But the manual explicitly says that nested substitution works only for 
`${...}' or `$(...)'.

With that the above is correct -- for certain values of `correct'.
