my favourite:

void foo(ref int a) {}

void main() {
   foo(42);
}

DMD64 D Compiler v2.068.2-b1:
  Error: function a.foo (ref int a) is not callable using argument 
types (int)

maybe there are more related issues in the bug tracker.

Based on a quick look in the C++ frontend some time ago, this 
should be quite simple to fix by inserting a check for 'rvalue as 
ref'  before the error message is printed. At the moment I have 
no time to figure out how dmd works and to implement this. May 
there are some edge cases, too.
