FWIW, in my experience 'type' (and 'value') are really unfortunate names for
class templates, if you want you code to compile stabily under VC6; both
correlate with our naming convention of "returning" types/values from
metafunctions, and that doesn't help the compiler. Without seeing the code
and errors I can't say if that's the case, but there is a chance that using
something named less provocative as a wrapper template can help here.
