Title: Micro optimization - Second Attempt

The intent is to do a quick review across the core modules to try to optimize them for V8, specially the low hanging fruits. So far, we have two things we want to optimize:

- "delete" is evil in V8, avoid the use of delete on objects.

- "try/catch" is slow, avoid the use of it when possible.
