I was surprised to find out that contains? checks keys, even on vectors. Is this idiomatic in some language? I think most new users to Clojure will find it confusing.
I propose that contains? checks values on vectors, leaving the behavior as-is for other collection types. And yes, I understand the existing behavior is consistent (at the data structure level). But it doesn't meet user expectations. > On Tue, 2008-09-30 at 17:29 -0400, Stuart Halloway wrote: >> For your specific case you should probably be using contains?, which >> works for both. > > No. contains? is meant for maps, i.e. when applied to vectors it > checks > against indexes: > > user=> (contains?
