Comment (by ramey):

 Comment:

 I find mpl print indispensable.  However the following should be noted
 somewhere:

 a) in order to work with GCC -Wall (or likely some more specific warning)
 must be set in the command line.  Actually I should be -Wsign-compare.
 This is the case with gcc-4.5.3

 b) The following only prints the first time

 struct a;
 typedef a b;

 mpl::print<a> // this displays
 mpl::print<a> // this doesn't display
 mpl::print<b> // neither does this.

 I don't think this can be actually fixed, but I would be nice to see it
 noted in the manual.
