Subshells aside, I have a hard time believing that "the process ID
of the shell" confuses anybody in practice. Even POSIX doesn't
overcomplicate this:
$
Expands to the decimal process ID of the invoked shell. In
a subshell (see Shell Execution Environment), '$' shall
expand to the same value as that of the current shell.
