As far as I can see from the user manual (I also tried placing some
`SCC`s), there's no way to easily add cost-centres to top-level
definitions. We can do things like:
{{{
f x y z = ...
=>
f = {-# SCC f #-} \x y z -> ...
}}}
but it becomes too much work once we have "equations" style definitions
like
{{{
head [] = {-# SCC head #-} Nothing
head (x : _) = {-# SCC head #-} Just x
}}}
Also, `where` clauses work differently after the transformations. Example:
{{{
f x y z = ...
where <can use x and y here>
=>
f = {-# SCC f #-} \x y z -> ...
where
