It is a program that iterates through several files and processes them. I wouldn't want to type all of that on the command line every time.

But that is exactly what you are doing every time you use string eval, you're creating a mini perl program, from stuff you typed on the commandline, might as well just use -E and avoid eval altogether 

$ perl -E " say @ARGV" say 6
say6

$ perl -E " eval qq!@ARGV!" say 6
6

I am also wondering why two other monks suggested it.

Branfart :) It is the shortest answer to your question, but its also the most dangerous one. See String::Interpolate
