[Insight-developers] STYLE: Un-necessary use of static_cast -- should we care?

[Williams, Norman K]

The problem with ITK in this context is that SetInput is overloaded.
There may be two different ways to set an input, and one may be picky, and
another more permissive.  The compiler will only sometimes be able to
determine what exactly the real pointer type is.  And even then I suspect
most compilers do not optimize away dynamic_cast.
