use 'x is None' instead of 'x == None'
The built-in None object is a singleton and it is therefore safe to
compare memory addresses with is. It is also faster, how much depends
on the object being compared. For a simple type like str I get:
| s = "foo" | s = None
----------+-----------+----------
s == None | 0.25 usec | 0.21 usec
s is None | 0.17 usec | 0.17 usec

patch: simplify Boolean expression slightly
The context variable is either True, False or None. Abbreviate it as C
and we get the following truth table where the second column is the
original expression and the third column is the new expression:
C | C or C == None | C is not False
True | True | True
False | False | False
None | True | True

match: use self.exact instead of lambda
self.exact uses a set and does not need an extra copy of the files
