Well, yes and no. GHC actually does a decent job when given very
imperative code with references and mutable arrays.
Now the type I use to wrap the references to get type safe l-values
and r-values makes it tricker, and ghc lacks a crucial optimization
for specialization of constructor returns.
With that in place I think the code could be quite performant.
