In this PR I fixed type checking of the dependencies array. It's a very simple fix, all I had to do is to trick TS into thinking that the generic T parameter is being used, like this:
private readonly __type?: T;. Without this, TS sees the generic as unused, and ignores it completely in the type checks.I also added tests for types, so in the future cases like these will be caught earlier.
