According to TakeCommand Help v.11:
It's probably an artifact of my ignorance but I can't find answers for the following questions.
@PERL[expression] : Executes the specified Perl expression (requires Active State Perl 5.10).
- Does @PERL block until expression is evaluated? i.e. Does TakeCommand/TCC wait until the Perl expression is evaluated?
- What return values (if any) are provided by @PERL?
