If templates were required, the call to explicit_convert_to could instantiate a template instead of resorting to implicit conversion. I'm not saying that one is better than the other, only that both should be supported.
Here I'm lost.
#include <iostream> int foo( int ) { return 1; } template <class T> int foo( T ) { return 2; } int main() { std::cout << foo(42L); } The presence of the template inhibits the implicit conversion of long to int. Sometimes this is desirable and sometimes it is not, and if the syntax used to call foo requires it to be a template, potentially useful implicit conversions can't kick in. I do understand that there is no such requirement in Conversion. Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
