--parser babel

Input:

class Base<T> {}

interface SomeExtensionClass<T> {
  create<A extends typeof Base<T>>(this: A) : InstanceType<A>
}

Output:

SyntaxError: Unexpected token, expected "," (4:12)
  2 |
  3 | interface SomeExtensionClass<T> {
> 4 |   create<A extends typeof Base<T>>(this: A) : InstanceType<A>
    |            ^
  5 | }

Expected behavior:
This is valid typescript should be able to format

Instantiation expressions are parsed correctly in the next version, not published yet
