Re: a better way to write this
Using collections: (every? true? (map #(%1 %2) [func1 func2] (repeat common-argument))) where func1 func2 are your functions. and common-argument is the argument shared by them all. Or something like this: (every? true? (map #(%1 %2) [type-pred bounds-check contact] (repeat element))) Granted this won't be the fastest method in the world (macros would probably be better), as there's going to be a fair amount of object creation going on, and now instead of invoking 3 functions, we're invoking much more. But at least this code is readable, and fairly easy to understand.

This is slightly shorter: full-test (fn [element] (every? #(% element) [type-pred bounds-check contact])) On Friday, November 4, 2011 10:51:43 AM UTC-6, HamsterofDeath wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 here's a part of my clojureoids-code: (let [type-pred #() bounds-check #() contact #() full-test (fn [element] (and (type-pred element) (bounds-check element) (contact element)))] (filter full-test (:game-elements @world-atom)) is there a way to write the full-test in a way that doesn't force me to repeat the function constant text pattern inside the and? -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.14 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJOtBgfAAoJENRtux+h35aGDTAP/RM2mXcu7+HlH0gVHPcZ2bH0 31MEGk5ysup06vgntmxOClaNV9PcxQ1g3bu44YTWDKy3S5RWiD+yB+LkAV0e8xvM p8A64giicfaxI2qncmEpgjodrUn8Yg4vde9X5pQRRaQaWTG56jlLUClorOy62W2q gsvNaehEZa6MZiG6yQOEQ1j0sS438bkmCsqxmHAs2ZmAkb9osTatKECK4sAZRx6l 31KHRFEWx8piiND5vxUGeqlf/CHC3r9VCgBc86q/nnH2CL4cofrkv6mXUYxHikPS AVbT8Qtuonh+twoGLH6t+TYCrVIgiAmnO9IOWFqpdkcX+us3V+ETvXSAVfuf6mCM +pS3Ps0+VndU31/ufZ0pdki/DxlMJiMVPSS1l/Z76671rCQe+dBjFDSU4e+4y9du sj0h1VNQ/tKzQ0jCGb9AF6MHoy51b4dpaqjwuJ4HQscH3L9ruG46dTZs5+IvWb5v 2htp5jQNY25e05qbT2tjPVTKT7C6kZ5S3dMlAfQnQxIaHrIm92IHzq3bhF3xMbgy Yh5sC66y/O4BPZnCvcKY6RF6wBlSZ/vLVOYAasvV89bWanUvv5vgFlNWysNoNF0o eCFhm1NQmvDoqTa0okx3kN5LeoVgGZdfmkEcVNIvVNUFYzht6ffGNaESb3YWFMlO buElt55CDSzWlvkBwqPU =A6jg -END PGP SIGNATURE- -- You received this message because you are subscribed to the Google Groups Clojure group.
