--- Comment #1 from Nick Treleaven <nick at geany.org> ---
Under https://dlang.org/spec/statement.html#NonEmptyStatementNoCaseNoDefault
grammar block it says:

> Any ambiguities in the grammar between Statements and Declarations are resolved by the declarations taking precedence. 

For:
> ref () {return a;}() = 0;

A declaration `ref () {return a;}` gets parsed, not an ExpressionStatement. So
I think this issue is invalid.

It is unfortunate that the function literal syntax starting `ref` or `auto ref`
was added, when the function/delegate keyword starting forms can already handle
those.
