Hi Frank,
I use a right-hand-side-only delimiter for this purpose.
(math (concat (around* "<nobracket>" "q" "|") (rsub "C") "=y"))

Dear all,
I wonder how to input the symbol for restriction of function? Now I input,
say,
(math (concat "q|" (rsub "C") "=y"))
which will generate, in my opinion, an incorrect spacing (see the space before and
after "="). I also suspect that this is semantically incorrect.
Best wishes,
Frank
