Just to be a little more clear about what is happening here:
Perl 5 tended to treat things as strings if you use them as strings, or as
numbers if you use them as numbers. Perl 6 is more strict about that, but
makes an exception for specifically numbers and strings; if you have
noticed the class "Cool", that's a class whose subclasses are string and
number classes, and which tries to make one into the other if needed.
Subs aren't Cool. [ :) ] They are objects of type Sub, which is *not* a
String (nor has a Stringy role, nor is a subclass of Cool). Perl 6 wants
you to explicitly make a string in this case; and as there are multiple
strings one could want (the name? a summary of the definition like .gist
makes? the full definition like .perl is intended to make but IIRC doesn't
yet? something else?) you need to specify exactly *what* string to get from
a Sub object.
