Yes, something like that would be nice. Of course, you could say, C<given
caller.MY{'$_'}>, but I think there's two separate things going on here:
1) There should probably be something in the syntax to allow for
retopicalization of the up-scope topic
2) It may be useful to have some way to allow single-parameter blocks to
take the up-scope topic as a first parameter.
