Comment (by ncohen):
Yoooooooooooo !
> Yes, the limitations of the algorithms are precisely documented. This in
particular to prompt creative people to find better algorithms that will
work in a more general setting (it's non trivial).
(with birds singing in the background) it is indeed a delight to see this
small piece of software grow everyday, becoming more powerful and
accurate. Wouldn't it be nice though if those cases raised an exception ?
Some forgetful users may not read the documentation. Some functions that
use this one may not contain the warning in their docstring. Our innocent
users may be led to believe that this method and those that may depend on
it always returns correct results even though its docstring states the
opposite.
And (without birds singing in the background) : it's not "other people's
job" to add these tests in a code they did not write.
Nicolas. C'est dangereux ces trucs, tu sais bien... C'est des choses qu'on
fait dans son code perso, pas dans du code qu'on partage.
