The following module was proposed for inclusion in the Module List:
modid: Pollute
DSLIP: Rdphp
description: Many modules can now be bundled into one.

rationale:
Modules export their functionality into the package where they are
invoked, this is called "name space pollution." If you want to have
all of your packages use the same several modules, you can use
Pollute.pm to create an "include file" kind of module which will
import all the imported symbols from the other modules. When Pollute
is used, it takes a census of the symbols. Then Pollute() is called
and new symbols are aliased into the caller's caller's package.
Pollute::Persistent is an even tighter way of creating an "include
file" module: its import method clobbers the caller's import method
with a self-modifying version of &Pollute::Pollute that maintains a
persistent list of the symbols that need to get updated when the
"include module" is used; opposed to regular Pollute, which requires
all of the modules' import methods to be run every time.
