Subject: Re: Array#first is not Array#[0]

Ok, I got it. So Array#first is a matter of optimization. I thought it
was syntactic sugar that the Ruby interpreter translates to Array#[]
(0).
But I understand now that Array#first is not there for my coding
convenience but rather for computational speed.

Thanks for clearing it up!
