I am having a problem with the above statement, in particular the part
"although the current dir is also always searched".  To source a script
you can use one of two builtins, "." or "source". According to the man
page, for the "." builtin:

"Files in the current directory are not read unless `.' appears somewhere
in $path."

For the "source" builtin:

"Same as `.', except that the current directory is always searched and is
always searched first, before directories in $path."

As all examples in this email thread were using the "." builtin the above
statement didn't make sense to me. To be honest, until I reread the man
page, I always thought that both builtins were doing the same identical
thing. Learned "my" something new for today.

Hopefully I did not misreading what you were trying to state.
