From @AlexDaniel

*Code​:*
say ‘abcefghij’ ~~ / .**{0..^2} /

*Result​:*
「ab」

I expected 「a」

*Code​:*
say ‘abcefghij’ ~~ / .**{2^..^2} /

*Result​:*
「ab」

I expected it not to match anything (as if it was 3..1).

10​:30 Zoffix teatime​: I see another bug with it​:
10​:31 m​: say "xxxxx" ~~ /"x" ** { -5..-1 }/
10​:31 camelia rakudo-moar 8cf083​: OUTPUT​: «「xxxxx」␤»
10​:31 Zoffix It doesn't check whether -1 was its own doing or something that came from the Range
