Are quotes around hash keys a good practice in Perl?

Question

Is it a good idea to quote keys when using a hash in Perl?

I am working on an extremely large legacy Perl code base and trying to adopt a lot of the best practices s

Answer 1

I go without quotes, just because it's less to type and read and worry about. The times when I have a key which won't be auto-quoted are few and far between so as not to be worth all the extra work and clutter. Perhaps my choice of hash keys have changed to fit my style, which is just as well. Avoid the edge cases entirely.

It is sort of the same reason I use " by default. It's more common for me to plop a variable in the middle of a string than to use a character that I don't want interpolated. Which is to say, I've more often written 'Hello, my name is $name' than "You owe me $1000".
