Hi,
not sure whether it's a bug or simply a known limitation of the parser:
loop foreach i varnames(sth)
doesn't work, but
vn = varnames(sth)
loop foreach i vn
does.
I know that this array-loop thing is fairly new in any case.
This is with 2021b.
cheers

In context "sth" must be a list, and for a list L you have
loop foreach i L
print "$i" # or whatever
endloop
So you don't need varnames(). Am I missing something?

No, I think you're right in this context, I hadn't thought of that.
But while we're at it, what about other array-producing functions, so
using them on the fly is not supported, right?
thanks
