After thinking about this for some time, I actually think we should drop
the whole feature. I guess it would be too confusing for a lot of
TypoScript users to understand what the difference between parser-level
properties and interpreter-level properties are. I think it's already
pretty difficult to explain things like "You can use all stdWrap
properties for the TEXT content object as well, but you can't use it on
IMAGE, only on the .stdWrap subproperty of IMAGE cObjects" and so forth...

IMHO adding such superglobals would just increase confusion...

I would prefer something that is clearly distinguishable from normal TS
properties.

Maybe something like this:

<PARSER_INSTRUCTIONS>
  addToList(plugin.tx_myext_pi1.pidList, 15,37)
  appendString(plugin.tx_myext_pi1.logInMessage, "Regards, the staff")
</PARSER_INSTRUCTIONS>

cheers,
