Possible optimization for the selector module

[flesler]

This reduces the code size and makes things more straight forward. But could be slower than the actual code...

This adds a LOT of overhead :(

The performance overhead isn't worth the code improvement.

The code to be removed is redundant with attr, maybe a refactoring is a better approach.

I don't see why "redundant". Using attr() is the logical approach, it just adds too much overhead.
