This is generally considered to be bad style, and -- who knows? -- you may even wind up confusing yourself this way. If you want to modify the contents of a list, use foreach.
You know, I can understand people who say "I find modifying list elements using an alias confusing", and I can understand people who say "I'm fine using all the features Perl gives me, including list aliasing". I don't know what to think of people who say "I'm fine with modifying list elements in a block, but only if the keyword is foreach
, if the keyword is map
, it confuses me". Those aren't the people I would want to hire.
