Re^23: Why? (each...)

ikegami,

Actually, at a certain level of granularity, your car does indicate a road. At least more so than it would indicate a peanut-butter-and-jelly sandwich. And I think that is what Argel is getting at. He is simply suggesting to novice users to memorize the (LIST) idiom when initializing a hash or array and forget about understanding why for now. In his effort to do this, he writes a simplism but that seem not so harmful.

Argel,

On the other hand, this is sundialsvc4 asking this, and from what I've seen of his posts, he's more than ready enough to comprehend the full truth: that the parenthesis are just there for operator precedence so the comma expressions get evaluated before the assignment.

In fact, I also used to trip up now and again while initializing an array or hash and use {} or [] instead of (), but thanks to ikegami's presumably good-intentioned opaqueness, I actually paused and thought about why parentheses, and thus it will never be an issue again for me as I finally understand.

Actually, at a certain level of granularity, your car does indicate a road. Really? Which road does it indicate? I bet you want to answer "the one it's driving on", but it's neither driving nor on a road. So again, which road does it indicate? He is simply suggesting to novice users to memorize the (LIST) idiom when initializing a hash or array and forget about understanding why for now. As he said, that is what he tried to suggest. "Use (LIST) to initialise a hash or array" is vastly different than "Parens indicate a list." The former is explains one method of initialising a hash. The latter is incorrect and doesn't even help in the specific situation it's suppose to help.	[reply]

Which road does it indicate? No particular road, just the presence of roads in general. My reasoning is sound enough on this point, so I won't engage further. After all, this is Perl Monks, not Phenomenology Monks. "Use (LIST) to initialise a hash or array" is vastly different than "Parens indicate a list." I'd say "different", but without the adjective "vastly". But again, I won't engage further. I've had my say. I see your point. I acknowledge it's correctness. And I am grateful for your effort, and most especially, my new insight.	[reply]
