It works for me:

sage: var("x, y")
(x, y)
sage: x+y == x+y
x + y == x + y
sage: bool(x+y == x+y)
True
sage: if (x+y == x+y):
....:     print 'yep!'
....:
yep!


Unless you mean that you want bool to be automatically applied to every equation? Since Sage follows the convention that "False" means "I couldn't see how to prove this was true", this would mean that pretty much every equation would automatically be False from the get-go and so you couldn't do anything with it. For example, (x-2)*(x+3) == 0 would be False (x could be 9, for example).
