This used to work up through 2.061:
//////////////////////////////////
module app;
struct A {
auto opAssign(lazy void foo) {
foo(); }
auto opOpAssign(string op)(lazy void foo) {
foo(); }
}
void bar(int x) { }
void main () {
A a;
a ~= bar (1); // OK
a = bar (1); // Error: expression bar(1) is void and has no value
}
//////////////////////////////////

This regression also affects classes, which previously worked up through 2.060:
//////////////////////////////////
module app;
class A {
auto opAssign(lazy void foo) {
foo(); }
auto opOpAssign(string op)(lazy void foo) {
foo(); }
}
void bar(int x) { }
void main () {
A a = new A;
a ~= bar (1); // OK
a = bar (1); // Error: expression bar(1) is void and has no value
}
//////////////////////////////////
