The problem is that postblit is not overloadable, so make it
overloadable, and problems with overloading will be solved.

(assuming copy construction gets taken care of)
Collections must be filled somehow, so they are inherently
mutable, immutable collections need a whole different design
approach, it doesn't look specific to postblit.
* pure is difficult
Purity depends on written code. Running impure code in copy
constructor won't make it pure.
