From @AlexDaniel

Although S/ / / is not documented (Raku/doc#437), it is still relatively well-known and is commonly used.

However, I was surprised to see that TR/ / / is not implemented (that is, non-mutating transliteration). This looks like an inconsistency to me. If we have S/ / /, then why not have TR/ / /?

So I am creating this ticket to point out this inconsistency.

One might say that this ticket should be created in the spec repo, but, after all, S/ / / is not present in the specs, so that would be a bit inappropriate.

FWIW to add it one will need to hack this part​: https://github.com/rakudo/rakudo/blob/de0533c4d4c9f425ce22432a8e4555ded27cba91/src/Perl6/Actions.nqp#L7999-L8055

See the implementation for S/// for more inspiration​: https://github.com/rakudo/rakudo/blob/de0533c4d4c9f425ce22432a8e4555ded27cba91/src/Perl6/Actions.nqp#L8057-L8234

Basically you'd be checking for ｢ $ < sym > eq ' TR '｣, which of course has to be first added here as ｢<sym=[tr|TR]>｣ https://github.com/rakudo/rakudo/blob/nom/src/Perl6/Grammar.nqp#L3853
