in reply to Re^2: Pass array, then clear
in thread Pass array, then clear
I did not suspect that the subroutine made a copy of the memory address
It doesn't. You do, with the my($data) = @_; snippet. If you directly manipulate the argument, it works as you expect:
sub clear_it { $_[0] = []; }
Because you're then working on the original reference, not on the copy you made.
