Now all three commands complain about a type object being passed when an
instance is required:
$ perl6 -e 'say +Failure'
Invocant requires an instance, but a type object was passed
in method Numeric at src/gen/m-CORE.setting:15733
in block <unit> at -e:1
$ perl6 -e 'say "abcd".index("xyz") == 0'
Invocant requires an instance, but a type object was passed
in method Bridge at src/gen/m-CORE.setting:5603
in sub infix:<==> at src/gen/m-CORE.setting:5521
in block <unit> at -e:1
$ perl6 -e 'Failure == 0'
Invocant requires an instance, but a type object was passed
in method Numeric at src/gen/m-CORE.setting:15733
in sub infix:<==> at src/gen/m-CORE.setting:5323
in block <unit> at -e:1
Is that reasonable or what would be an adequate error message?
