Is this something that eventually might be added to set.mm?. Our informal convention has been to prefix non-italic letters with underscore, like _i, so _<letter> will clash with a few that already exist. How about a single quote prefix, 'a 'b 'c ... like in Lisp 'foo to abbreviate (quote foo)? That would not clash with anything in set.mm except ''' in AV's mathbox (for alternate function value) which could be changed.
