For function imports with no parameters the service may support an alternate syntax of omitting the parens. For maximum interoperability, the service must still support calling function imports with the parens.

Currently we require function imports to have open/close parens, even if they have no parameters.

Services could be more lax in allowing clients to call parameterless function imports with no parens.
