I see no big advantage over class variable initialization, but there are

some disadvantages:
1. It's incompatible to other Smalltalks (well, so is {}...)
2. For binary storage of methods, you need to decide whether
    it should be re-evaluated when the code is loaded into an image.
I could list some more (minor ones) but I think you get the idea.

So, I prefer class variables with initialization.
