Below newStorage[T] and newStorageOfCap[T] call getUnderlyingType(T), which shouldn't work because T is a type and getUnderlyingType takes an openArray argument. However it works due to a Nim bug where T is treated as a value of its type.
To make this work with and without the bug fixed, add an additional getUnderlyingType overload that takes a type openArray parameter instead.
