Description bearophile_hugs 2010-10-11 18:13:29 UTC 
Maybe this is a duplicated error report, but I haven't found it.

Current dmd 2.049 doesn't support nested functions with "auto" return value:

void main() {
    auto foo() {
        return 1;
    }
}


DMD shows:
test.d(2): no identifier for declarator foo
test.d(2): semicolon expected, not '{'


But this is an useful feature to have because "auto" is becoming increasingly important as lazy Ranges often have a very complex type.

Comment 2 bearophile_hugs 2011-06-26 05:10:19 UTC 
In DMD 2.053 the error messages are:

test.d(2): function declaration without return type. (Note that constructors are always named 'this')
test.d(2): no identifier for declarator foo()
