Perhaps, but consider the starting point of one argument:

my(
    $foo,
) = @_;
[download]

compared to:

my $foo = shift;
[download]

I use the shift approach because it gives me a clean starting point and lets me extend my methods (or subroutines) easily. Having said that, I try to avoid extending public methods and prefer to create new methods when appropriate. But perhaps I'm drifting away from the original question a little..
