Re^4: Lose first element of hash in hash ..

While most of the suggestions are good, I take objection with two:

What's wrong with using barewords as hash keys? The quotes mostly clutter up the syntax, and it's rare that you want a function call inside a hash key access.

Instead of using global / glob filehandles and closing them manually, I recommend to use lexical filehandles, which will close automatically when the enclosing scope is left.

OK, I retract the bareword comment; I guess it's a matter of circumstance and personal taste. I also always use lexical filehandles, but I habitually close them as soon as I'm done with them. This can be done with an explicit call to `close`, or by introducing a separate scope. The latter form is especially recommended when locally modifying `$/` and such things.	[reply] [d/l] [select]
