I am trying to figure out if it is a bug or feature that inside of a transaction function my vector is being turned into an Arrays$ArrayList

it is definitely problematic as it makes testing a txfn directly give different results then when it is called inside of a transaction

e.g. (sequential? x) fails for said ArrayList

and (or (sequential? val) (instance? java.util.AbstractList val))

feels... gross

to be fair I am on a slightly older version of datomic (0.9.5372)

I will test with latest and provide a minimal test case, was just wondering if this is a known thing
