Would that not be:-
say "Basename is $(str.subst(rx|.*/|, ''))"
I thought when you were interpolating method calls you had to put brackets
$(object.meth), so that you could still write things like:-
$fh = open "$id.txt"; # OK, maybe my open syntax isn't right
Or is it that you can do:-
say "$object.meth()";
But not:-
say "$object.meth";
And the later (...) distinguish that we are doing a method call?
Or am I completely wrong? :-)
