Re: how to use std/std_unordered_map.i

The files in Lib/std are common support implementations used by the more
advanced STL wrappers. I'm afraid Perl is not one of those. What is
required is a new file Lib/perl/std_unordered_map.i. This would be a copy
of Lib/perl/std_map.i and modifications to turn it into a
std::unordered_map.i. Probably not too hard to do.
