Well, it would be harder for *me* to type. I imagine Hiredman has
these symbols bound to some short but little-used key sequences. If
you're not using your C-c bindings for anything else, you can
pick four of them and use them for this.

Huh. Isn't a unicode composition symbol harder to type than comp? If it's
for readability, I'd rather go with the emacs hacks.

Hi Eric,
Looks good; nice job with complement too. Of course you can add it to the
Emacs Starter Kit ;-)

Ask on #clojure about this. Someone (hiredman, I think?) has a macro
that rewrites code using some funky unicode characters. I can't find
it at the moment, but it might be what you're looking for.

Hi Paul,
Thanks for sharing this. It seems like the best compromise between the
desire to keep my code brief (at least to my eyes) without wanting to
introduce my own custom function names for global functions.
If you don't mind I'd like to add this to my fork of the Emacs Starter
Kit (will cred
Yep, you have to use flip and it is not so elegant

And less than 3 if one is honest. Haskell is spicked with rather
unmotivated "`foo` x"s which simply means #(foo % x) in a
clojure is nice too for the example but if you'd add functions and
they have arity more than 1 haskell gets better (imo of course):

dont think so, haskell can be hard to read but not for those reasons
F. e. filter when the sum of elements are even:
Prelude> filter (even.sum) [[2,3],[3,3]]
[[3,3]]
i think is pretty readable ;-)

Well, for those who use emacs, you could always make it *look* like it was
pretty... For example:
(eval-after-load 'clojure-mode
'(font-lock-add-keywords
'clojure-mode `(("\\"
(0 (progn (compose-region
(match-beginning 0) (match-end 0)
,(make-char 'greek-iso8859-7 107)) ;; a lambda
I think the minimal character count for composition and partial functions in
haskell are some of the reasons that haskell code is so impenetrable to
non-haskell hackers. Feel free to rig up crazy unicode characters to any
identifier you want in your own code, just don't ask me to read or debug
Coming from Haskell, where composition and partial functions are cheap and
free in terms of character count, it is actually pretty discouraging to have
to spell it out in Clojure for the same effect. Some of the cases where you
"should" be using multiple expressions in Clojure would be perfectly c

Possibly because bang functions indicate "Here be drago

I think comp is nice and short, personally. Partial is okay, and the
long name helps discourage me from using it when I should be using #()
instead - partial is a bit slower. And if you find yourself wanting to
nest #() forms, it's not that bad to switch to partial, and it may
serve as a warning si
