>My understandding is that it applies to string delimiters or [] shouldn't be used as delimiters at all.
No. Its a very powerfull way to use delimiters
example
#DEFINE dcTest Cetin
?'Hello dcTest'
?[Hello dcTest]

Update:
I never use [] as array delimiter. I always use () because of the way it's colored.
