I think there's confusion stemming from there being *two* methods
being wrapped, one has the guard, and the other has its internals
elided, and we assume there is a guard.
Method one is called "size":
around 'size' => sub {
my $orig = shift;
my $self = shift;
return $self->$orig() ##### Guard
unless @_;
my $size = shift;
$size = $size / 2
if $self->likes_small_things();
return $self->$orig($size);
};
Method two is called "sequence":
around 'sequence' => sub
{
my $orig = shift;
my $self = shift;
my $sequence = uc shift;
# Do lots of things with $sequence and then
#### NO CLEAR GUARD
return $self->$orig( $sequence );
}
And as he describes, the issue he experiences is predominantly with
the second of these, which makes sense, given there is no code that
*we* can see with the guard mechanism.
