Research direction
Start by reviewing the inline table example in the issue and the two proposed parsing options. Determine which text-format behavior should be adopted for shared tables; done means the chosen behavior is specified clearly and reflected consistently in the relevant parser expectations.
Written by the indexing model from the issue text.
Description
Tables can be written in WAT in inline form and the addition of shared in the text format means that inline table expressions (e.g., (table <type> (elem ...))) are difficult to parse: the parser would potentially have to look past two tokens now, shared and i32|i64 to see if a type appears that indicates we should be parsing an inline format.
Here's an example of the problem:
(table shared i64 (ref null (shared func)) (elem (ref.null (shared func))))
Some options for what to do here:
- disallow inline table expressions with
shared; after all, these can be expressed other ways - force parsers to lookahead more tokens
