May i customize basic operator (such as 1==3)?

[kanchy kang]

__eq__ method can resolve this problem only for class object.
what can i do in the following case?

a = somefuction(...) #a is stringType

a == "1234"?

my simple requirement is:
in some validation statments, such as, failUnless(a == "1234")
if the result is true, it's OK. otherwise, it prints a automatically.

also, i know we can implement failUnless(...) to satisfy this,
failUnless(a == b, a, b)

but i think, if we can override "==" for any type, it will make things 
conveniently...

regards!
