I don't like this feature. Because:

1. it would reduce code readability.

   class LibClass {
     int foo() { return 1; }
     string bar() => "hi";
   }

   Mixing lambda syntax and normal function syntax looks messy.

2. Just only reducing 7 character is too small benefit.

   auto foo()=>expr;
   auto foo(){return expr;}

   With more complex function signature:

   ComplexReturnType!(..) foo(T, U, V)(T t, U u, V v) if (...)=>expr;
   ComplexReturnType!(..) foo(T, U, V)(T t, U u, V v) if (...){return expr;}

   Ratio will fall further.
