Explicit Variables again

I wouldn't worry too much about making your scripts "compliant" with
There are probably some users who run with it on, but not many.
The IDE itself doesn't really use it except during compilation only, it
seems - here's where the dizzyingly long chain of commands that gets
invoked when you click "Apply" finally sets the script, handled here in
button "Template Editor" of stack "revscripteditor.rev":
command scriptCompile pObject
local tOldPreserveVariables, tOldExplicitVariables
put the preserveVariables into tOldPreserveVariables
put the explicitVariables into tOldExplicitVariables
set the preserveVariables to sePrefGet("preserveVariables")
set the explicitVariables to sePrefGet("explicitVariables")
put the result into tScript
set the script of button "revCompileObject" of me to tScript
put the result into tResult
if tResult is empty then
put the revAvailableHandlers of button "revCompileObject" of me
set the preserveVariables to tOldPreserveVariables
set the explicitVariables to tOldExplicitVariables
# The script should be unset because it could cause issues with idle
set the script of button "revCompileObject" of me to empty
IIRC, explicitvars were seen as too cumbersome to work with, since as a
truly global property the required that EVERYTHING you're using comply
with it, and too many plugins didn't.
So rather than require every developer to comply with the requirements
of explicitvars just in case, they came up with that clever trick of
turning it on only during compilation, and immediately turning it back
off again (or to whatever its value was, which is usually off since most
folks who turn it "on" do so from Prefs, where it's not really "on"
until that moment of compilation.
In brief, I'd just blow it off and move on to other tasks....
