for! crr.glob!("**/*.er"), pth =>

Since Path.glob! returns a generator, we should introduce a Generator T class (The type definition for iterdir is incorrect).

@mtshiba
Thanks for the review!!
Are there other issues that need to be added, such as the definition of Generator?

[mtshiba]

No, Generator is a compiler-builtin type.

Thank you!
