I did not want to make this a discussion about contains? per se, but
about the general design philosophy about dealing with type erros
(which I think is a bigger issue, IMHO).
But it is a bit difficult to avoid noticing that contains? is a bit
unintuitive, so to say.
Even with vectors
(contains? [1 5] 5) being false sounds somewhat strange.
I understand the initial intent, like this:
(contains? {'a 5} 5) being false
But the end result with strings and vectors is a tad unintuitive...
