Good point, and a good reason for a macro.

Of course those would work, but I got sick of typing them over and
over.
(map-method length ["mary" "had" "a" "little" "lamb"])
(map-method indexOf ["mary" "had" "a" "little" "lamb"] (int \a))
I find typing # and % repetitive, so this is just a little syntactic
sugar.
--~--~-~--~~---
Or anonymous function literals?
user=> (map #(.length %) ["mary" "had" "a" "little" "lamb"])
(4 3 1 6 4)
user=> (map #(.indexOf % (int \a)) ["mary" "had" "a" "little" "lamb"])
(1 1 0 -1 1)
