This is a typical java -> ruby switcher question :-)

If you want rename method call "subscribe" in class "Newspaper" to a
method call "register", then how do you know if

foo->subscribe(a,b)

should be renamed? You can only look at heuristics like: it has two
parameters like the subscribe method i want to rename, so i hope it is
a call of a Newspaper.subscribe and not of RealEstateContract.subscribe

Another question:
And how do you find all files where we look for subscribe ?
This can be very hard to tell. require is way too dynamic.

Think about it and further problems or just search groups.google
to find more discussions about the problem.
