That's true, unfortunately.

I mean that the source builtin already behaves differently
depending on the state of the shell. The bash documentation
for the source builtin states:

> If filename does not contain a slash,

I thought that simply adding the BASH_SOURCE_PATH 
variable would end up adding a new if statement to the
documentation. Something like:

> If the BASH_SOURCE_PATH environment variable
> is defined, bash will search for filename in the
> directories specified by it first, falling back to
> PATH if not found.

I interpreted that as adding complexity to the builtin
and sought to avoid it by taking another approach.
The result would be documented like this:

> If the -l option is passed, bash searches the directories
> specified by BASH_LIBRARIES _PATH only. PATH is ignored.

I thought that was simpler.
