If the code is so simple that I can hit a button and have my IDE generate my code for me then I really question why I need to write the code in the first place.

A simple example of this is generating getters/setters. Autogenerating the code works great 99% percent of the time. The problem comes in for that 1% case where a non-templated getter or setter is needed. That special case is easy to lose track of in the forest of automatically generated code. Groovy solves this problem by automatically generating all of the getters/setters for you, but if you need to you can still override the automatic definition with a specific implementation.

I won't argue you with that too much magic can be a bad thing. However, for the code I typically generate with my IDE I really think I'm wasting time and bloating my code.
