DateType is a workaround for this
bug to demonstrate that we could
have a type-checking-time wrapper for datetime that doesn't change (or almost
doesn't change) the implementation, but fixes up two very annoying behaviors of
the stdlib datetime module:
-
a
datetimenow won't type-check as adate- it still inherits at runtime (the implementation is, after all, not changed) but it doesn't inherit at type-time. -
there are separate types for naive and aware
datetimes.
There's a very small bit of implementation glue (concrete @classmethods for
construction on the Naive and Aware types, and a few functions that do
runtime checks to convert to/from stdlib types).
