I think it would be better to use an adaptive policy later. Something 
like: all methods will be inlined if they are evaluated enough times. Say 
a method with 10 literals will be inlined if it's evaluated 100 times. A 
method with 100 literals will need 10000 runs, etc. (note: i just made up 
the numbers).
