Why not just specify that :flat always expands before MMD dispatch?

I'm not sure it's just multi-dispatch; it looks like all signature checking.
The foo() in the example I q

From S06:
sub foo($x, $y, $z) {...}# expects three scalars

To flatten before the list is even passed into the subroutine, use the eager
list operator:
foo([,] eager @o

In this example, $x, $y, and $z are positional args. I would expect C<

Yes, exactly. I thought :flat and :slurpy were symmetric.

Exactly. Snippets from S06:
