Firstly, everybody needs to remember that ?: is now ??:: :-)
And yes, if $a and $b are equal but evaluate to a false value, you
probably want to attach some truthfulness to the value for boolean
sake. I wonder if you shouldn't also return a bool::false for the
other case just to be explicit:
sub &infix:<myeq>(Str $a, Str $b) {
return ($a eq $b) ?? $a but bool::true :: bool::false
}
Suddenly I'm suffering a visual overload of colons though.
