Difference in String#split behavior

[dazuma]

String#split behaves differently from MRI in certain cases.

" ".split(" ")  # or equivalently, " ".split

In TruffleRuby 21.3.0, this yields [" "].
In MRI (both 2.7.5 and 3.1.0 tested), this yields [].

Indeed, thanks for the report (" " as argument is special and awk-like splitting, same as no arg).
@bjfish Could you fix it?
