Subject Re: [Text, Lang] Matching two CharSequence instances
Date Sat, 02 Mar 2019 16:59:09 GMT
Is your proposed method a stepwise charAt comparison across both, assuming
non-null and equal length?
Doesn't seem like a bad idea, though I'm curious whether there's a use-case
where toString() on both and comparing isn't more expedient.
