If "smart" proposal is, we'll no longer say.

It's only used once.

Set whether we're in a pipeline in order to determine how to parse the
hash. The error message changes as a result, since the `hash` never
enters the block.

This ensures we clean up always if the callback throws.

This doesn't work because the `type` values are not compatible.

This is no longer true, now that we return `tt.hash`.

These are parsable only in follow-on proposals, not in the base proposal,
so we'll introduce that in a separate PR.

This seems to parse fine. Should it?

This impact private fields as well as smart pipeline, providing a clearer
error message for both.

If a property access is computed, e.g. a[b], then it's in topic style. Currently,
this isn't accounted for. Test & change ensures this doesn't parse.
