I think I like the idea of adding time trace scopes for concept checking;
Corentin and I are also exploring this locally to understand our concept
performance issues.
however I think it would be much more useful to have fine-grained statistics -
for example, identifying which concepts (and optionally, with which template
arguments) are the most time-consuming.
That said, this is a good start, and I am not opposed to going with it as is.
