[SciPy-Dev] requesting code review: added close matches to constants.codata.value()

[Nathaniel Smith]

Another option (don't know if it's a good one):

class ConstantKeyError(KeyError):
    def __str__(self):
        key = self.args[0]
        similar = ...
        return "Constant %r not found -- perhaps you wanted one of:
%s" % (key, ", ".join(similar))

-n
