Dunno, delegates already have quite overloaded and ambiguous syntax.

--- Comment #3 from Andrei Alexandrescu <andrei@erdani.com> ---
In the notation

    ref elem => elem.x = 1

it is unclear whether `ref` refers to the return value of the lambda or the parameter. These do work:

    (ref elem) => elem.x = 1
    ref (elem) => elem.x = 1

(The second would be rejected because it returns a reference to a local.)

I'll close this, please reopen if appropriate.
