Sorry, I don't really get it.  First of all, utility/value_init.hpp 
doesn't have a "set".  Do you mean "swap"?  But secondly it's really up 
to the compiler whether or not those functions are inlined.  An "inline" 
keyword would only be a hint to the compiler to do so, in this case. 
But as value_init.hpp provides the complete definitions of the function 
templates, it shouldn't be hard for the compiler to apply inlining.  Are 
you saying that gcc would /only/ inline those functions, when they are 
declared as inline?

Kind regards,
