That doesn't look very promising :(

The documentation for the Show typeclass has this very example:

The summary? you need to define either showPrec or show, the latter of which is
simpler, it is just a - String.
So:

Based on the package versioning policy [1], A.B is a major version, so if you
know that it works with 1.2, then it is reasonably safe to specify the range =
1.2 1.3, as no major api breaking changes should occur within the 1.2 range
(ie, 1.2.1 to 1.2.2, etc)

I also think it would be really good to have some documentation that explains
the type system and how to do neat things with it in terms that a reasonably
competent haskell / ML programmer could understand.

As a more general response, be careful with parsing dates, because as far as I
can tell, it is easy to print times (with formatTime) that cannot be parsed
(with parseTime). Specifically, if you strip the padding (of zeros or spaces)
there is no way to parse it back in. So parseTime . formatTime

The problem is that [] alone is not a concrete type - that is what the error is
