Few ideas to reduce template bloat

[sebastien.f]

This problem reminds me of a recent paper written by Bjarne Stroustrup (and others) describing and evaluating a technique named “generalized hoisting”. It’s applied  to the C++ STL iterators and removes lot of code bloat and increase performances surprisingly.
I found it a great read (as often with Bjarne.S) I thought you may find it interesting too.
It says the ideas apply to the D language too.
