Summary:                    "trap" (with no args) specification does not match

First, what is most important here is that it is recognised that
the current wording is inadequate, and promises something that it
is unable to deliver.

The workaround method that can be used can vary, I'm sure there are
many possibilities - your scheme (note 4133) assumes you know in advance
what traps are to be altered, which will often be the case, but is not
suitable for a general solution.

Regardless of that, we need to do something to make it clear that simply
using $(trap) is not sufficient in any current shell as a method of
restoring
what was there before.
