If we have a new namespace ``BASH_SOURCE_PATH'' for the scripts to be sourced, it would be neat to have an option to specify the namespace exclusively.Should these be the default semantics for BASH_SOURCE_PATH?Even if the option is not supported, I think the default semantics should still reference PATH and the current working directory as fallbacks because some libraries may want to set BASH_SOURCE_PATH,
As I said, I'm not sure a library changing the value of a global user setting like that is good practice.
`unset -v var' is not required.That was a POSIX invention as a compromise between implementations.Hmm. Then, is the example of `unset' irrelevant?
It means it wasn't added for orthogonality or to make the language cleaner;
it was added to allow applications to force a particular behavior in the
face of default behavior differences by existing implementations. And this
was back in 1990.
