I would like to highlight methods a little differently from local variables. Consider:

 p p # two method calls
 p = 0 # an assignment
 p p # a method call and a variable reference

The rules for telling variables and methods in Ruby apart are clear, but not simple to parse.

(unfortunately the forums were taken down, so the link to http://code.licenser.net/boards/4/topics/show/3#Examples-of-separated-versus-shared-storage-in-Ruby is broken)
