The problem is the following: using this kind of syntax makes much more complex the task of simplistic source code analyzer, because of the "function call" in the loop bounds. Indeed, unless using a CPP, the macro is interpreted as a function here by tools such as Clan (at least it's current version embedded in PoCC).

Sure.  I just didn't know what name to pick.

Could you make these changes, or do you want me to send in a patch?
(I could ask the student, but it would probably take me more
time to explain it to him than to just do it myself.)
