Description Erkki Lindpere

Granted, these don't happen often, but it would be helpful if Eclipse could assist simplifying complex boolean expressions that have redundant checks. For example this from http://thedailywtf.com/Articles/The-Test-of-Truth.aspx : 

return (test == true)? ( (test == false)? false : true) : ((test == false) ? false : true);
// can be reduced to 'return test;'

Ideally, it should be able to simplify if-else statements as well.

Move to JDT/UI

Would make a nice project to implement for somebody interested.
