editor support doesn't reflect this - another fyi item.

to explain my question better: i thought 'forall' was intended to be
used more like a quantifier in math, traditionally preceding the
elements being quantified, as in the following way to define a subset
S of T:

forall x in S, T contains x

or maybe it was meant to be used in a more english-like manner (or at
least python-like):

T contains x forall x in S
