In v6.7 and later (possibly earlier too; I didn't check any version
prior to v6.7), the Dictionary entry for the executionContexts includes
this note:
Important: The value of the executionContexts may be
changed in future versions of LiveCode, it is not
recommended to write code that depends on its contents.
The web version of the Dictionary, though reportedly a few versions
behind more recent versions (to the confusion of a few forum readers),
also includes that note:
https://livecode.com/resources/api/#livecode_script/executioncontexts
Interesting. I stand corrected - the executionContexts is documented
after all. It *is* a bit out of date, though, as it doesn't reflect the
additional parameter(s) for behavior objects. The additional parameter
was added in a way that cleverly maintains backward compatibility,
although if you need to trace your way through behaviors you need to
take it into account.
