Apostrophe in subroutine call
|

Hi, I'm trying to understand a bit of opensource perl and I have come across something I have never seen before. When various subroutines are called, they have an apostrophe somewhere in the middle of it, per (see underlined parts of code): sub HttpInit { local($arg, $db, $pw, $headers, $agent) = @_; defined &Http'Init || do { unshift(@INC, $HOME); require "linkhttp.pl"; }; &Http'Init($arg, $db, $pw, $headers, $agent); } This one calls itself! Does anyone know what this means or what it does? Examples of this are littered throughout this particular package. Any help is appreciated. ROBBO
