Why is that not constructive? You use a generic term to introduce it to those who don't know. Every one of us surely wasn't born to know something until we learn something, correct? God forbid, it's a different story to melodramatically sensitive folks who can't take good comments for bad ones...

Moreover, it's always a good idea to include a code demonstration to show what you mean by what you've said. Many times we say a bunch of things trying to decipher a topic, but only to result misunderstanding or confusion to those who read our posts. As they say, a picture is worth a thousand words.
