RFC: std.*.concept convention

[Baz via Digitalmars-d]

Hello, I remember the first post about this, a few monthes ago, 
and the concept of concept is interesting. Do you think it'll be 
possible to extract a collection of delegate from an agregate 
which verifies a concept ?

- get the concept from an interface
- check if this concept is in a struct
- extract the concept methods from the struct

=> almost polymorphic struct !

Don't know if it's clear.
