Feature Request: 'set --erase' for multiple/all scopes

[daveman1010221]

Hello!

I'm not in the practice of requesting features, but I feel this is one that is missing. It seems that un-setting a variable can be more difficult than it really should be, requiring a number of logic checks to ensure a setting is really gone. Could we have a:

set --ERASE foo

wherein, it actually un-sets the variable, regardless of scoping? I will even submit a pull request, if you agree. :-)

Thanks.

There is set --erase to "just erase a variable", but it only erases the closest scope.

If I'm correct, what you're asking for is "erase in all scopes"?

I'd probably just allow multiple scopes to be specified with --erase, so you can do

set --erase --local --global --universal foo

or

set -elgU foo

for short.

That sounds great.
