Replying to [comment:121 chapoton]:
> * more generally, maybe one could try to avoid using assert, and better
raise precise Exceptions ?
Just a side note: as discussed on sage-combinat-devel, assertions are
preferable in the following situations:
- For checking the internal state of the program
- When the caller should *not* catch the exception
- In time critical locations
Beside, nothing prevents from writing a meaningful message in an
assertion check.
Cheers,
Nicolas
