I was right on all but `true if 1..2`. WTF? Is there some flip-flop nonsense going on?
yeah, I missed that one, too! And was completely shocked when `true if 1..2` didn't match `if 1..2; true; end` they're handled by…
…different code in the parser, but I spent ~20 min looking for why they don't behave the same and don't yet see a good reason.
you also get different results in different REPLS. irb returns true, nil. pry, ripl, etc returns nil, nil.
I got the same results (I wrote the quiz into a file and then ran pry/ripl/irb w/ the file set as stdin)
Well according to your issue it's fixed in 2.4 and just needs a backport.
