SFINAE vs static if
Substitution failure is not an error. Wasn't that where if the
template use/instantiation failed it would go onto the next one (and
hope one of them worked)? Although it could work assuming you have
enough templates to handle the cases, being able to determine if they
quality (as in D) is a superior solution.
Reminds me... Wasn't there a problem with the min/max in C++ where to
correctly make it work there was some 90+ templates for the STL? (I
think it was rejected). Makes you wonder sometimes what they are
thinking when they decide this stuff.
I do miss using a language like C++ on my daily job, but then I read
articles about "great ideas" like SFINAE.
