in reply to Correct keys in hashes

I used to always quote them. But that took forever so now I don't. However for the parnoid it's probably better. Lest some day you do something like...

my($count)=0;
sub name() {'autoname'.$count++}

$foo{name}='bob';

I'll still probably skip the quotes until the it day bites me since I don't type so quick.

That doesn't have anything to do with quoting keys. $foo{name} will always be interpreted as $foo{'name'}, and there's no way you can disambiguate that by using or not using quotes.

If that was supposed to call your name function, you should have written it with parens, as in $foo{name()}. In fact, you should get in the habit of never calling functions without parens. (And of using sub strictures.) That will disambiguate almost every case of possible confusion that crops up in Perl.
