Thanks, I got it! I agree, it would simply be a great feature.
While playing with your examples, I noticed that Sage can
in fact display them as you want but only partially. For example,
----------------------------
riemann_abcd(x) = function('riemann_abcd',x)
riemann_abcd._latex_ = lambda: '{\\mathcal R}_{abcd}'
view(riemann_abcd)
----------------------------
works! but
------------
view(riemann_abcd(x))
------------
doesn't work. So surely, there are issues. However I guess,
it shouldn't be difficult to fix given it already works partially.
Cheers
