In the attached code partial specialization of struct apply in struct
METAFUNCTION2 should be rejected according to C++ Standard 14.7.3/3:
A declaration of a function template or class template being explicitly
specialized shall be in scope at the point of declaration of an explicit
specialization.
What's more troublesome is a fact that specialization in METAFUNCTION2 seems to
affect the template in METAFUNCTION. The program produces:
int
double
double
while I would expect:
int
HELPER
double
