This is totally sweet. I've often fleetingly wondered if it would be
possible to create iterators from strings. This is really creative and
intuitive. I'm not from the Ruby world, but I love it!
My only suggestion would be to require an explicit call #toFunction() so
that it would be more obvious that it is an iterator function and not
require an extra line be added to the Enumerable functions. (if
(iterator) iterator = Function.from(iterator); )
So, for example:
['FOO', 'BAR', 'BAZ'].map('toLowerCase.toArray'.toFunction());
var divs = someDivs.findAll($H({hasClassName: 'myClass', visible:
true}).toFunction());
['apples', 'oranges', 'plums'].sortBy(['replace', /^(..)(.)/,
'$2$1'].toFunction());
What do you think?
