+C<allocation> is "best effort" in nature. It will take the C<bin>,
+C<chargenumber> etc hints from the parameters, but will try it's bvest to
+fulfil the request anyway and only bail out if it is absolutely not possible.
+
+Sometimes you need to restrict allocations though. For this you can pass
+additional constraints to C<allocate>. A constraint serves as a whitelist.
+Every allocation must fulfil every constraint by having that attribute be one
+of the given values.
+
+In case even that is not enough, you may supply a custom check by passing a
+function that will be given the allocation objects.
+
+Note that both whitelists and constraints do not influence the order of
+allocations, which is done purely from the initial parameters. They only serve
+to reject allocations made in good faith which do fulfil required assertions.
