@car222222 I disagree. The picture clearly shows that a thin space is added in front of a class 1 atom (Op), which is not at all desirable. `\mathopen` has the...

@FrankMittelbach I still disagree. The added space before a `\mathop` is a clear oversight. There's no reason for the space after the colon in ```latex \begin{align} &f\colon R \to S\\...

Agree with @josephwright about the name. Or, maybe, `\int_if_range:nnTF`? No problem with the empty part denoting the relevant infinity, although such tests are already doable with `\int_compare:nTF`. A single integer...

@blefloch This is really interesting. What would be the complexity of the transformation by `\intset_gremove`? I'm expecting quite a lot of shuffling around.

Not sure this is the right place. The suggested fix indeed works, but it *might* break existing documents, although this would be quite a rare situation, because using `\qedhere` in...
