Code Generators or T4 Templates, are they really evil?

Question

I have heard people state that Code Generators and T4 templates should not be used. The logic behind that is that if you are generating code with a generator then there is a bet

Answer 1

Code generators could be considered a code smell that indicate a flaw or lack of functionality in the target langauge.

For example, while it has been said here that "Objects that persist can not be generalized", it would be better to think of it as "Objects in C# that automatically persist their data can not be generalized in C#", because I surely can in Python through the use of various methods.

The Python approach could, however, be emulated in static languages through the use of operator[ ](method_name as string), which either returns a functor or a string, depending on requirements. Unfortunately that solution is not always applicable, and returning a functor can be inconvenient.

The point I am making is that code generators indicate a flaw in a chosen language that are addressed by providing a more convenient specialised syntax for the specific problem at hand.
