Inspired by ModPerlize I crafted the attached script to analyse usage of globals in the TWiki core. The analysis was run on the checked in code as of 17the June 2004.

If you run the script on a TWiki that has plugins installed, it will analyse the plugins as well.

Global refs are references to the variable outside the module where it was declared. Local refs are refs within the file where it was declared.

Seems to me all those with 0 global refs could be converted to "my" variables now, today, without affecting anything else.

Session-specific globals are now held in a single TWiki "session" object. This topic is therefore redundant. DeleteMe.
