(Not sure why this issue was closed last year — I've re-opened to implement something to add something like one of the fixes above.)

Oops, old habits :)

@u-fischer Thanks Ulrike — I've been trying to improve my variable names and this one was particularly bad :) Code should now be: \NewDocumentCommand \xmapsto { m } { \mathrel...

The problem is that `\l__um_symfont_label_tl` is somewhat extensible, in that yes by default it is just "operators" but if a second maths font is loaded for a different range it...

Exactly my line of thinking :) Originally unicode-math-table.tex was fairly limited, and the radical code was written very long ago. When I started adding to the "math classes" I never...

Thanks, this looks great to me. Sorry I can’t analyse this in detail right now — does this address the issue entirely or is it only part of the solution?

@RuixiZhang42 — thanks, I see what you mean. I think the default should be to use the font-specific scaling present in the font metadata itself (i.e., override `\DeclareMathSizes` by default)....

I think only catching the false case makes sense, which overcomes the “order” issue and keeps the number of excess csnames down. If someone comes along with a complex need...

I've wondered about something like before, too, although I didn't come up with anything in particular. Do you think it would make sense to create a wrapper around `\aftergroup` instead?...

I guess the idea behind that implementation, as ugly as it is, is that I think the syntax is slightly more natural. Can you think of a way to simplify...
