The boost cast library used to have an implicit_cast template, which
was stricken because it didn't work and was wrong. However, since
then, I've often found that I needed such a beast. Usually this need
arises when I want to induce a conversion to something that might be a
built-in type, for which constructor syntax actually does a C-style
cast:
T(x) // watch out if T is a pointer!
Here's what I think might be a correct implementation:
template <class T, class U> T implicit_cast(U const& x) { return x; }
template <class T, class U> T implicit_cast(U& x) { return x; }
Thoughts?
