Avoid $` $& $' in libraries
Subject: Pessimal $` $& $' in libraries Corrected: lib/diagnostics.pm lib/Getopt/Long.pm lib/Pod/Text.pm os2/OS2/REXX/REXX.pm $' $` $& eliminated from all the known *.pm. Btw, by this I proudly introduce usage of $+ in standard perl modules ;-). p5p-msgid: <199702210207.VAA03560@monk.mps.ohio-state.edu>
