: Yep. You missed the bit that says that multimethods only dispatch on their
: invocants (i.e. the parameters declared before the colon). What you wrote
: would probably induce a compile-time error:
:
: Inconsistent declaration of multi foo($me:...)
Actually, the problem is that they're consistent, not inconsistent. Perhaps:
Undifferentiated declarations of multi foo($me:...)
On the other hand, it might just fall into the category of:
Redeclaration of &foo($:) at line 123...
