Re^4: Use global flag when declaring regular expressions with qr?

[Anonymous Monk]

It is up to the reader to decide if that increases or decreases maintainability :)

On the one hand, I really like how there are so many similarities with shell scripting, in terms of syntax at least. On the other, it's a bit confusing to keep track of so many implicit behaviors. I was always told to be explicit whenever possible as it makes code easier to reason about. I'm afraid to forget what variables like @_ do if I don't use them often enough! :D

Thanks for the tips!

You can avoid the punctuation variables and use long names (e.g. @ARG for @_); see https://perldoc.perl.org/perlvar#SPECIAL-VARIABLES.
