+Per a discussion with Martin, these are just a few cases missing in
+ExplicitReferenceConversionExists and ExplicitReferenceConversion in
+mcs/convert.cs
+
+The relevant piece of the spec that is missing is: 13.2.3 "Explicit
+Reference Conversions" is missing the last two conversions that only
+apply to the generics compiler. These are:
+
+"* From a one-dimensional array-type S[] to
+System.Collections.Generic.IList<T> and its base
+interfaces, provided there is an explicit reference conversion from S
+to T.
+* From System.Collections.Generic.IList<T> and its base interfaces to
+a one-dimensional"
+array-type S[], provided there is an implicit or explicit reference
+conversion from S[] to
+System.Collections.Generic.IList<T>. This is precisely when either S
+and T are the same type
+or there is an implicit or explicit reference conversion from S to T.
