The following code compiles without errors void foo() { return false; } void bar() { return "bar"; } void main() { foo(); bar(); }

Not a bug, see http://www.digitalmars.com/d/changelog1.html#new0116 "Can now return an expression from a function returning void"

> http://d.puremagic.com/issues/show_bug.cgi?id=438 Can you point to where this is documented in the language spec and maybe some past threads discussing it? I'm really curious as to the reasons behind the choice. Thanks, Brad

I can understand accepting "return void" from a void function, as in C++, but I would expect returning anything else to generate a compile error.
