Summary: list/Nil/Cons mismatch with local generic function
Description:
def isSorted[Element](sequence) where Element: System.IComparable[Element]
{
| head::nextOne::tail =>
isSorted(nextOne::tail) && (head: Element).CompareTo(nextOne: Element)
!= 1
| []
| _::[] => true
}
isSorted ([1,2,3]);

simpler example:
def isSorted['a](_)
{
| x1 :: x2 :: xs =>
isSorted(x2 :: xs) &&
x1.CompareTo(x2) != 1
| []
| [_] => true
}
isSorted ([1,2,3]);
this is strange, because removing ['a] makes it work
