I'm opposed to the policy to add asserts like in ODE, for the following reason: 
In unlikely situations these pieces of code might be reached (esp. the one in 
the normalize methods). It is not very nice if a user reaches such situations 
and the whole applications crashes as a result.
Printing warning, throwing exceptions (if they are used), returning/setting NaN 
are ok. Terminating the application is not, as it might happen outside the 
testing phase.

my 2 cents,
