Re: Why is -- in the output of declare -p x?

[Peng Yu]

"Consider the ramifications of the latter paragraph of Koichi's
response. As was stated, it is potentially useful for a program that
processes the output of `declare -p` to be able to assume that the
second word always defines the attributes and that the variable
assignment always begins from the third word."

The above is an argument for why `--` should be kept. But what if the
2nd argument starts with - then it is an option, otherwise it is not.
This is an equally valid argument why -- is not absolutely necessary.
Thus, for human readability/brevity, it should not be there.
