sync tests to value.js changes
change alter/add to append for consistent naming that doesn't conflist with DOMxList.add
null-safe each() conversion
only() should work for non-Element list members
only(): more rigorous match test and always return a list (again)
fluent add() proving less useful than informative add(). besides, native DOM lists aren't fluid either
more thorough testing of D.extend()
all() now can take functions to act/customize while gathering
add except() (inverse of only()) for lists
back out valueFor changes
s/except/not
don't rely on elements.js impl details
