lib->unimport ???

[bill]

The version of lib.pm installed in our system includes a definition
for a sub called unimport. It is not used elsewhere in lib.pm,
and it is not mentioned in the POD for lib. Also 'perldoc -f
unimport' turns up nothing (same for 'perldoc -q unimport' for that
matter). So why does lib define unimport at all? I became aware
of it when I found "lib->unimport" while reading some fairly eminent
module's source, from CPAN. The author of this module has produced
some very widely used modules, so I don't think this person would,
without good reason, break the precept of never going outside the
published API.

So, what's the official status of lib->unimport ? Should it be
regarded as if it were part of lib's published API?

And what about unimporting other modules besides lib?

'unimport' is the method called when you write

no Module;

just like 'import' is the method called when you write

use Module;

See 'perldoc -f use' for more information.
