On the face of it, this sounds good as an *alternative* distribution.
I imagine some sites want to get only the core language, and none
of the modules unless they are explicitly required.

Eh, don't know about this one.  This is one of the "bugs" Python has
with their distribution system.

Are you proposing something like this:

	Standard distribution: 
		1: Everything (core, docs, standard modules)
	Alternative Distribution: 
		2a: core language (+ pragmatic modules)
		2b: standard modules
		2c: docs (possibly split into tutorials and reference)

Or some other mechanism?

That would avoid the buggy Python distribution problem.  The 2a..2c
dists should all untar into the same directory, producing the same
set of files that the dist #1 produces.

It shouldn't matter if 2a..2c is further subdivided, so long as it's
a "small" number of files to download.

How much of the problem is the size of the install vs. the size of
the download?

While this is a concern, I think this is a lesser concern thatn building
a version of perl out-of-the-box that makes more sense for embedded
uses of Perl (e.g. Perl within Mozilla, PalmPerl).

Er, how about:


	A permanent ad-hoc working group should be created to discuss the 
	perl6 standard library as the project comes closer to shipping code.

	The charter should include selection criteria for adding modules
	into the core distribution, as well as design criteria for 
	modules that aim to be included into the core (e.g. adhering
	to perlstyle).

Add a section on memoize to the list of modules to add, and I'll retract
RFC 228.
