[perl #125215] [BUG] 10 ** -1 is a Num, but should probably be a Rat since it can in Rakudo

[Christian Bartolomaeus via RT]

As a status update: 10 ** -1 is now a Rat:

$ perl6-m -e 'say (10 ** -1).WHAT'
(Rat)

9.0 ** -1 is also a Rat, and there is no type check error:

$ perl6-m -e 'say (9.0 ** -1).WHAT'
(Rat)

$ perl6-m -e 'say (9.0 ** -1)'
0.111111

9 ** 0.5 is a Num:

$ perl6-m -e 'say (9 ** 0.5).WHAT'
(Num)
