[lworld] javac allows Value Type generic parameters with var

[James Thompson]

Local type inference with the use of var masks at the source level generic
type parameters, therefore it is trivial to create a new generic collection
of Value types.

e.g. var list = List.of(Point.create(1, 1), Point.create(2, 2));

where Point is a Value type. This will compile without
