Actually, blowing the dust off my own diploma thesis, i found several instances of arctan, exp, ln, log - all roman.

I fully agree with that. > (But I get your point.) Once i came to the intermediate conclusion that we better work on the level of character escape sequences than on the level of egn(7) syntax, i considered all escapes, no matter whether they are needed in the context of eqn(7). >> For some character escape sequences that render to nothing in >> groff -Tascii, i decided to use descriptive renderings >> enclosed in angle brackets in the past: >> >> \(sc SECTION SIGN >> \(de DEGREE SIGN >> \(ps PILCROW SIGN >> \(CS BLACK CLUB SUIT >> >> Do you consider that desirable for cases like the above, too? > Indeed, I think this is a sensible and readable way to go for -Tascii, > particularly for characters likely to be used in eqn(7). Following that, my inquiry on already elicited positive feedback from Werner Lemberg. So i'm quite hopeful that we can get this done and make eqn(7) useful for your intended purpose.
