[CLJS-426] subvec function not behaving consitently with invalid subranges

Fri, 23 Nov 2012 15:25:10 -0600

When using the subvec function with a as a parameter vector and a range that is not in the original vector, the function returns a value:

(subvec [1 2 3] 0 4) => [1 2 3 nil]

However, when using with seqs, it works as it supposed to:

(subvec (range 3) 0 4) => ERROR: Index out of bounds

This is because the validation of ranges is not happening at build time of the subvec type, this bug contains a patch that adds a new private `build-subvec` function into cljs.core.
