in thread What I Most Recently Learned in Perl, But Should Have Already Known
perl -MO=Deparse -e ' print "true" if 1'
If we do if 0 something even funnier happens:
$ /usr/bin/perl -MO=Deparse -e 'print "true" if 0'
But which is most amusing is the fact that the deparsed code generates a warning:
$ /usr/bin/perl -w -e 'print "true" if 0'
$ /usr/bin/perl -w -e '"???"'
Useless use of a constant in void context at -e line 1.
