You're not alone in that belief.  I've heard several people comment about 
how easy it is to code Smalltalk when exploring new solutions.

Static methods are a necessary evil in OO languages and should be avoided 
when possible.  The entire Java Math class is a perfect example of poor 
design because it's just a bunch of static methods.  It would have been 
*much* simpler to make numbers objects and allow -1.abs() type semantics.  
Anyways, my main point is that statics exist in Java to make certain things 
easier, not to allow the type of thing you describe.
