$ as
showNum n a = show a ++ x ++ show n
Pointsfree and explicit lambda notation I find can be very concise in
places, but make it quite hard to reuse or refactor code later - if you
can't read it, make a function/variable with a useful name so you can
later.

Just to follow those sentiments, the version I knocked out quickly

Why can't it automatically construct them then? Assuming we do have
a syntax for A list of objects, each of which is of some possibly
different type 'a', subject only to the restriction that a is a
member of typeclass Show, as the following:
ls :: [a where Show a]
Then I would

Very cool. I don't understand some (a lot of) parts though:
instance Show a = Reify (ShowConstraint a) where reify = ShowC
ShowC has type (Show a) = ShowConstraint a, whereas reify is
supposed to have type
