//: VCL_TEMPLATE_MATCHES_TOO_OFTEN
//
// A function template is selected by overload resolution only if no
// non-template requires equal or better conversions.  Some compilers
// (eg MSVC 6.x and 7.0, Borland 5.5 and 5.6) select the template
// incorrectly in a case like this:
// \code
//    class A {};
//    template <class T> void f(T);
//    void f(const A&);
//    void g() { f(A()); } // should call non-template
// \endcode
//
// The work-around is to explicitly give the template a worse
// conversion than the non-templated overloads:
// \code
//    class A {};
//    template <class T> inline void f(T t) { f(t, 1); }
//    template <class T> void f(T t, long);
//    void f(const A&, int);
//    void g() { f(A()); } // will call non-template
// \endcode
// In this example, the inline one-argument template will always be
// called, which will call the real function with an "int" passed to
// the second argument.  The templated two-argument function has a
// "long" second argument while the others have "int".  Therefore, the
// template will be chosen only if no non-templates match.

//  struct B: public A { B(); B(const B& b); ~B(); };
//  struct C { operator B(); };
//  void f(A);
//  void g(C c) { f(c); } // fails to call ~B() on 2nd temporary B
// \endcode
// Compilers will call c.operator B() to implement the conversion
// necessary to call f(c).  Some compilers will then create a
// temporary A by copy-constructing the temporary B to bind the
// argument of f.  Others will create a second temporary B by
// copy-constructing the first temporary B and bind the A-portion of
// the object to the argument of f.  Some compilers (at least Intel
// C++ 7.0 and 7.1) will create a second temporary B but forget to
// call ~B() when destroying it.  This can cause resource leaks.
