I know I can try this out but I will ask here anyway just to make sure 
my test is not being incorrectly done.

Can mpl::if_/mpl::eval_if be used to pick the type for which a default
template parameter is set based on some metaprogramming boolean test of
a previous template parameter type ?

I know that C++ allows a template parameter default to be set based on a
previous template parameter, but I don't know if mpl::if_/mpl::eval_if
can be used in this context.
