Detailed Description

template<typename Grammar, typename Fun>
struct boost::proto::when< Grammar, Fun * >

A specialization that treats function pointer Transforms as if they were function type Transforms.

This specialization requires that Fun is actually a function type.

This specialization is required for nested transforms such as when<G, T0(T1(_))>. In C++, functions that are used as parameters to other functions automatically decay to funtion pointer types. In other words, the type T0(T1(_)) is indistinguishable from T0(T1(*)(_)). This specialization is required to handle these nested function pointer type transforms properly.
