I agree, "eval is evil" ;)
But: In the last days I stumbled upon the problem, that we have lots of 
dependencies in the core classes that are impossible to mock in unit 
tests. Even if you only want to test a single method - if this creates a 
new instance using t3lib_div::makeInstance, there are actually three 
classes involved.
In short: having the possibility to mock t3lib_dib in phpunit 
environment would be a great help to ease and stabilize unit tests (not 
only for core classes).

Absolutely!
