FWIW, if I catch somebody where I work doing any of the following in
real code, I will become upset and talk with him/her:
- omit all whitespace following a statement or block
- omit whitespace between "for" and a loop variable name
- use $&
- use postfix "for"
- uncommented algorithm of this complexity
The following practices would disturb me, but I might let them slide:
- eval with implicit $_
- numeric operation on the left side of ||
- assign to $_ without local($_) or an equivalent
- omit final ;
- use O(3^n) memory when O(n) will do
Obviously, I was playing golf, not trying to be readable.
Best
-John
