recently in my perl programming hobby, I have found some pretty tricky things done by the pdevs
. (I am talking about Mr. Schwartz
and Mr. Phoenix
) One of these is the shift
command structures compared to the push
command structures. I would like to praise the creators (all creators) of perl 5.6.1 for thinking of shift
. I don't know much about the earlier version(s) and in what version these commands started in. Any info about this subject would be great.
But, the reason I am talking about these 2 commands is because recently a programmer told me there is no way to add on to the front of a list or array. I didn't believe this so I went into the blessed book, Learning Perl 3rd. I was happy to see that Mr. Schwartz and Mr. Phoenix included ways of adding on to the front of lists and arrays; also know as shift and unshift.
I would like to take a moment and thank these great pdevs for writing the great Learning Perl Series. These great books allowed me to gain honor in the eyes of programmers that I can show, even at 13, I can correct you at least once thanks to these guys. :-) Thanks Perl.
