How do I specify curly braces in the argument of \maple*?
I tried them as single characters, then they are gone after the Latex run.
When I try \{ ... \} instead, then the latex2qu run gets a stack overflow.
I can write square brackets instead and replace them in the .qu file, but that's very inconvenient.
Or is it a general necessity when you write your questions using Latex, that you have to edit the .qu file for similar shortcomings?
In Maple graded questions with the answer in Maple syntax. is it possible to disallow certain Maple commands in the answer?
