Are you familiar with "the halting problem"? :) (
http://en.wikipedia.org/wiki/Halting_problem)<http://en.wikipedia.org/wiki/Halting_problem>
The only reliable way to find if a particular program returns a runtime
error is to execute the program. For limited, targeted cases, (such as
importing modules) you could write an analyzer program which would be
*often* right -- but I could create a program that tricks your analyzer
into reporting a problem where none exists. Consider this:
import sys
sys.modules['foo'] = type(sys)('foo')
import foo
Your static analyzer would have a tough time recognizing that this program
would not raise a runtime error.
