Yeah, I am just trying to understand why it doesn't work without explicit import. Missing basics here: if rows=db.select() works and rows is known to be an instance of the class Rows, and Rows is recognized as a class and can be used to some extent (obviously, I am using it already, in rows=db.select() and beyond, without importing explicitly), what does it mean then that I can't use it? I mean, it's either visible or invisible. If it's already visible as a specific class, without being imported, why are its methods still invisible and require explicit import statement? I am suspecting that I am missing something very basic about namespaces. Earlier Leonel explained it, but I didn't understand the explanation.
