Balance is the key.
I have in fact just converted a functional algorithm
to an imperative one. Its the Felix inliner (which
inlines functions).
What happens is I replace a function call with
the body of the function being called with the
argument replacing the parameter.
The purely functional algorithm was
inefficient: it has to inline recursively,
and in doing so, it inlines the same function
calls multiple times, because there are multiple
calls. It is faster to 'cache' any inlining done
into a function so when *it* is called the inlined
version can be inlined.
The easiest way to do this caching is simply replace
the function into which inlining is done with the
inlined version :)
