in thread use of "use X"

I think what you were looking for is

$ perl -E 'BEGIN {our $debug = 1;} use if $debug // 0, warnings; say u +ndef' Use of uninitialized value in say at -e line 1.

although I would be inclined to go with an environment variable instead, to avoid having to edit the source code:

$ debug=1 perl -E 'use if $ENV{debug} // 0, warnings; say undef' Use of uninitialized value in say at -e line 1.
