[Insight-users] Functors and operator() const

[Julien Michel]

Dear ITK users and developpers,

Is there any reason why none of the operator() defined in ITK Functors 
(such as the itk::Functor::ACos Functor for instance) are declared as 
const ? It prevents me from reusing them inside some const methods, and 
it looks like they could have been declared const without any problem. 
Mutable does the trick, but I would rather avoid it if possible.

Thanks a lot for your reply,

Best regads,

Julien
