in reply to Count the number of return values from a subroutine

So do I, but $n = scalar foo does something completely different from $n = () = foo.

Observe, I have nothing up my sleeve! 

sub foo { 5, 17 }       # sub returning 2 values
my $n1 = () = foo;      # $n1 == 2
my $n2 = scalar foo;    # $n2 == 17

You forgot the general rule about converting a list to a scalar: "there is no general rule for converting a list to a scalar"!
