I don't suppose there is any "recall" utility on perlmonks that intercepts nodes that need to be reconsidered, edited, or slowly strangled into oblivion, is there?

That's what the Preview button is for.
The notion is that after you wrote, previewed, edited, checked, previewed, spell-checked, took another look, and only then posted, you have no rational reason to recall the post.
If you decide to post commando, you deserve the result, but can still amend them.
For example, if you realise that "Wait! Wait!" is slightly less good a title as, say, "Is there a way to recall or erase posts that have been submitted?", there's always usually an update button handy

Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.

Read Where should I post X? if you're not absolutely sure you're posting in the right place.

Please read these before you post! —

• How do I post a question effectively?
