#[inline] on generic functions

Should `#[inline]` tags be present on generic functions? As far as I know, they don't actually help with inlining, since generic functions are instantiated for each type during monomorphization. However, they may actually incur a cost on compile times, which are quite long for nalgebra.

The above statements should be tested with benchmarks, before doing anything about this, of course. Is there an argument for why the annotations should stay or are they just present out of habit?
