mismatch
fn
Tuple!(Ranges) mismatch(alias pred = (a, b) => a == b, Ranges...)(Ranges rs) if (rs.length >= 2 && allSatisfy!(isInputRange, Ranges))Sequentially compares elements in rs in lockstep, and stops at the first mismatch (according to pred, by default equality). Returns a tuple with the reduced ranges that start with the two mismatched values. Performs min(r[0].length, r[1].length, ...) evaluations of pred.
