Earlier I had written:

But apparently something in the transmission...
Anyway, below some code to illustrate my point, that you can easily
make something quite similar to class variables:
----<score script: staticTestBhv>----
on beginSprite me
put #init
tList = []
repeat with i = 1 to 4
tList.add(script("staticClass").new())
end repeat
put #test
call #mTest, tList
end
----</score script: staticTestBhv>----
----<parent script: staticClass>----
property pClass
property pClassTest
property pClassInstanceCount
on new me
pClass = me.script
if pClass.pClassTest.voidP then pClass.pClassTest = #static
pClass.pClassInstanceCount = pClass.pClassInstanceCount + 1
put #count, pClass.pClassInstanceCount
return me
end
on mTest me
put #count, pClass.pClassInstanceCount, #test, pClass.pClassTest
end
----</parent script: staticClass>----
-- Welcome to Director --
-- #init
-- #count 1
-- #count 2
-- #count 3
-- #count 4
-- #test
-- #count 4 #test #static
-- #count 4 #test #static
-- #count 4 #test #static
-- #count 4 #test #static
