This is one of the TODO items of G'Caml. 
You can hope that inlining of very simple generic values such as plus
will be available in near future, (but not in the next release, sorry.)
The inlining will occur only when:

  * The type of a generic value instance is statically known.
  * The corresponding overloaded definition is an identifier, such as
	(+) and (+.)

Inlining more complex generic values such as double 
(let double x = plus x x) will be another story...
