Imagine this:

&{$hashref->{'key'}}('key');

[download]

vs.

$hashref->{'key'}->('key');

[download]

Don't you think the second could lead to confusions?

I'm just trying to find what is best, I honestly prefer the first but I've never seen it until recently, so I am thinking maybe no one uses it because it may be harder to understand at first sight.

There are no stupid questions, but there are a lot of inquisitive idiots.
