Description
The current text format only allows specifying a shared function with an explicit type index:
(type $shared (shared (func)))
(func (type $shared))
I had thought (and so have others) that it might be nice to have a short-hand form for writing shared functions when printing WAT. There are some advantages to this: easier to read WAT, easier to write WAT manually, consistency with unshared functions, etc. But, for now, we have left this out because it's unclear how to best express this:
(shared (func ...))?(func (shared (param) (result)) ...)?
I'm opening this issue to track this for discussion and for future users who are interested in why things are the way they are.

Research direction
Start with the current WAT examples in the issue and the linked pull request review. Compare the two proposed shorthand forms for readability, consistency with unshared functions, and compatibility with existing syntax. Done means the discussion reaches an agreed syntax and documents why it was chosen.
