What you see is not what you get (WYSINWYG)

[ #20317 ]

Here's a curious result I ran across while working on a test suite.

$ perl -le 'print "All digits!" if 0x20 =~ /^\d+\z/' All digits!

Of course, the literal representation of that value in the program text is not the same as what Perl actually uses after it stringifies it.

$ perl -le 'print 0x20' 32
