Array vs. first element is completely useless.

A couple of uses:

  1. caller 
    sub c{ return caller(); }

print c();;
main (eval 16) 1

print scalar c();;
main

  2. each 
    print each %h;;
a 1

print scalar each %h;;
a

    [download]

Can you really not see a few other useful uses?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
