d S( s& Fixer for has_key().
Calls to .has_key() methods are expressed in terms of the 'in'
operator:
d.has_key(k) -> k in d
CAVEATS:
1) While the primary target of this fixer is dict.has_key(), the
fixer will change any has_key() method call, regardless of its
class.
2) Cases like this will not be converted:
m = d.has_key
if m(k):
...
Only *calls* to has_key() are converted. While it is possible to
convert the above to something like
m = d.__contains__
if m(k):
...
this is currently not done.
