Hash::int - provide a hash with native string keys


code

=begin code :lang<raku>

use Hash::str;

my %hash is Hash::str = fortytwo => "foo", sixsixsix => "bar";

=end code


Hash::str is module that provides the C<Hash::str> class to be applied
to the initialization of an Associative, making it limit the keys to
native string.  This allows this module to take some shortcuts, but
only have a very limited (a few %_) performance improvement, so you
should really only use this module if you're looking at getting those
last few percent.
