Hi there, I've tried to get the information if my package used the warnings and strict pragma. The $^W and $^H variables are to magical, so they contain nothing. The ${^WARNING_BITS} even contain nothing. How can I get this information?
package Test; use warnings; use strict; sub bintodec { unpack("N", pack("B32", substr("0" x 32 . shift, -32))); } print "\nW: " . bintodec($^W); print "\nW_BITS: " . bintodec(${^WARNING_BITS}); print "\nH: " . bintodec(${^H});
If you remove the "use warnings" or "use strict" there is no change in output. Even if you say "no strict" or "no warnings".

In reply to Find out, if "use warnings(all)" and "use strict(all)" are used by Tobiwan
