Incompatible types: Object vs void with invocation of grouped expression

[lucaswerkmeister]

Anything a = (print)("");

source/tmp/run.ceylon:1: error: incompatible types

Anything a = (print)("");
                    ^

required: Object
found: void

Found while investigating ceylon/ceylon-spec#1456.

As always, generated code, @noanno’d.

The compiler generates a let expression returning null.

Perhaps somewhat related to #2387
