+* Value Parameter
+
+       I believe that `Value Parameter' might have been introduced
+       after C# 1.0, also notice than in the treatment of Value Parameter
+       the parameters are defined in four categories:
+
+       Section 9.3 in the latest spec.

+New
+---
+
+       It would be nice to optimize the case of:
+
+               Method (new ValueType ())
+
+       So that no temporary is created, and we only use a newobj call
+       that remains on the stack, as opposed to ldloca, initobj, ldloc
+       call.
+
+NEW NOTES:
+----------
+
+       ImplicitStandardConversionExists and ImplicitStandardConversion
+       should always be the same, but there are a few diverging lines that
+       must be studied:
+
+                       if (expr_type == target_type && !(expr is NullLiteral))
+                               return expr;
+
+       vs:
+
+                       if (expr_type == target_type)
+                               return true;
