system(qq{perldoc $0});

Sorry, but no. I have much respect for TIMTOWTDI, but given that Pod::Usage has been in the Perl core for over 20 years and the question was already solved in the OP, then a solution that calls an external program that may not be installed, is brittle in other ways (PATH and $0), doesn't do the same thing as the OP is asking, and introduces a potential security vulnerability ($0 can be assigned to), is the Wrong Way.
