One should.  CPython's test suite includes test___all__.  I believe it 
imports every stdlib module, looks for __all__, and if present, tests 
that it works.  It probably executes 'from module import *'.  A side 
effect is testing that everything imports.  I am pretty sure that 
test___all__ has caught bugs.
