Updated behavior looks A enough:

09:17 < [Coke]> rakudo: ~[]<c>
09:17 <+camelia> rakudo b2072f: OUTPUT«postcircumfix:<{ }> not defined for type
                 Array␤  in method Str at src/gen/CORE.setting:10160␤  in
                 method Str at src/gen/CORE.setting:876␤  in method Stringy at
                 src/gen/CORE.setting:885␤  in sub prefix:<~> at
                 src/gen/CORE.setting:1272␤  in sub prefix:<~> at src/gen/…
09:17 < [Coke]> rakudo: ~5<c>
09:17 <+camelia> rakudo b2072f: OUTPUT«postcircumfix:<{ }> not defined for type
                 Int␤  in method Str at src/gen/CORE.setting:10160␤  in method

09:17 < [Coke]> rakudo: ~5{'c'}
09:17 <+camelia> rakudo b2072f: OUTPUT«postcircumfix:<{ }> not defined for type

Closable with tests.
