No difference.

Currently something like:
multi submethod infix:<as> ($self: Str) {...}
multi submethod infix:<as> ($self: Int) {...}
or
multi sub infix:<as> (MyClass $self, Str) {...}
multi sub infix:<as> (MyClass $self, Int) {...}
: Also, what's the point of making a whole grammatical category for "coerce"

In the current synopses there is no "coerce" grammatical category
any more. Everything is subsumed under infix:<as>, at least this week...
There's some discussion about whether it should simply be:
method as (Str) {...}
method as (Int) {...}
maybe with an "is deep" thrown in for good measure, but we haven't
quite got there yet.
