{ emit[T] } is not equal to { emit[T] }

[jiribenes]

The following code causes an weird "{ emit[T] } is not equal to { emit[T] }" error:

def fix[T] { one: T => Unit / emit[T] } { stream: => Unit / emit[T] }: Unit = {
  try stream() with emit[T] { value =>
    fix {one} { one(value) }
    // ^ [error]: { emit[T] } is not equal to { emit[T] }
    resume(())
  }
}

Fixable by

fix[T] {one} { one(value) }
