That is true , but the error message is not correct. In my typeof registration
I have registered vector6 with Typeof. This is not the registration that is
lacking. I guess that VC7.1 goes off the rails somewhere close by but, fact is
that the error message is pointing to the wrong place on this occasion.
FWIW I dont really see this as a problem for Typeof, which does provide good
diagnostics in simpler cases. I am just pointing out that, when the
error-checking is not helping as in the above case, then an alternative approach
is to use Typeid to find out what types your type is made up of. This is
particularly useful with e.g. mpl both because types are likely to be
complicated and because its not always possible to know the exact mpl type your
type is made of.
