I read through the 3.x Functional HOWTO, and it only seems to require a few minor updates. The attached patch:

• adds a forward link to skip the theoretical discussion in the first section.
• remove stray extra comma
• clarify what filterfalse() is the opposite of.
• (more significant) Describe compress(), the combinatoric functions in their own section, and accumulate().

Updated version of the patch:

• uses 'r' instead of 'N'.
• removes the old outline and some notes at the end.
• minor rewriting.

LGTM.
