Topic: ✔ What is this notation

I came along an expression that looks like this:

 {in map_to_list m2, forall x : prod_eqType K V, m1 !! x.1 != None}

I got it from move/hasPn:

I cannot figure out what is being said here,

I tried Locate "{ in _ , forall _ : _ , _}". and various of other variants (mostly truncating stuff from the right) but couldn't find anything.

You can always Set Printing All (or Set Printing Notation) in those cases.

Note that while using Locate " stuff ", the _ need to be enclosed by spaces. Ie, "... _}" won't work, you need "... _ }" instead.

And you can also use Locate on single tokens, for instance Locate "in" would have worked here (of course it displays a bit more than what you are looking for).
