question about GHC API on GHC plugin

[Mike Izbicki]

Thanks!  Now one more question :)

The code Andrew Farmer showed me for getting dictionaries works great
when I have a concrete type (e.g. Float) I want a dictionary for.  But
now I'm working on polymorphic code and running into a problem.

Lets say I'm running the plugin on a function with signature `Floating
a => a -> a`, then the plugin has access to the `Floating` dictionary
for the type.  But if I want to add two numbers together, I need the
`Num` dictionary.  I know I should have access to `Num` since it's a
superclass of `Floating`.  How can I get access to these superclass
dictionaries?
