So GHC leaves it to the user to specify sharing. If you want an
expression shared, let bind it and reuse.
Does GHC treat where and let the same in this regard? Or in code, are these
treated the same?
where is just sugar for let.
Well, they have different scoping properties because they're in
different syntactic classes in the parser (let is an expression whereas
where is a modifier on statements), but other than that yes they're the
same.
