Hi, I have a problem trying to correctly understand the docs in the section where the ::request::global is explained (Internals).

The question (attempt to preserve functioning tcl scripts when they are "cut'n'pasted" into rivet pages) is put in a way that (seems to me) it warns the developer that "global" is meant for persistence whereas the ::request::global command is for making into Rivet traditional "global scope" variables. (I don't see any other possible reason for bringing up the problem in the documentation). Am I misunderstanding the whole stuff? I wrote a sample script using ::request::global, global, ::global in turn trying to have persistence, but obtained only variables that are created every time I reload the page.

<? global visits #or ::request::global visits or ::global visits

set visits([clock seconds]) [env REMOTE_ADDR] foreach {t ip} [array get vists] { puts "-> $t $ip <br />" } ?>

My comprehension of the docs is maybe unadequate, but I suggest to reformulate the paragraph in a more schematic form.
