Hi Mattihas :-)

One of the major problems with Anyones heavy use of MPL is, as I understand,
its compile time performance.
I cant remember the references but this is mentioned ..."compile time is a
precious resource when using MPL" or something similar
I think in the MPL leaflet on the files section. It is also mentioned in my
Templates the complete guide  book Vandevoord & Josuttis
I am waiting for David Abrahams book to come out. I am sure there will be
some useful info
on the subject in it.
Dont get me wrong MPL is an important subject and the consensus appears to
be that you have made a good start.
But there is a point where compile times severely affect the way I code.
It is no fun and expensive having to work with slow compile times.

(If people bang on about it  the MPL guys may take notice... ;-) )
