The obvious three possible variants I listed above are equivalent to the language lawyers and the compiler ;-). This change is about dropping the need for ".hash", and I think a faithful, boring and mechanical conversion that tries to preserve the intent of the original author would be more appropriate. It is entirely possible that some places where the original said E2[E3] were easier to understand if it were *(E2 + E3), thus we may want to further rewrite such a place to (E2 + E3) instead of &E2[E3] after the mechanical conversion. Thanks.
