I'd think so, too.

Error: Too many arguments passed to &foo?
Presuming that multiple *%slurpy_hashes are allowed, I'd say that...
sub bar (+$a, *%overflow, *%real_overflow) {
say "[%overflow{}] [%real_overflow{}]";
}
bar(:a(1), :overflow{ b => 2 }); # [b 2] []
bar(:a(1), :overflow{ b => 2 }, :c(3)); # [b 2] [c 3]
But it seems to be cleaner to disallow multiply *%slurpies and just go
with the error.
