Return values

Most your remarks have to do with a wrong code documentation, right?

For the Language library i can say that the $lang variable is in the language file, so if it's defined in the library developers will not know there is something wrong with the language file they want to load.

For the Validation library when will the methods return NULL?

You should have some patience the EL developers are hard at work to get their bread and butter application out of the door which is already late.
