Make sure that 'length' can be inlined (Fixes #97)
Make sure that 'length' can be inlined (Fixes #97)

Previously there was a cycle in the dependency graph of functions,
consisting of {stream, clone, length, unsafeCopy}. This was causing GHC
to mark one of these functions, length, as a loop breaker.

This commit breaks this down this strongly-connected component by
removing the edge from length to stream.
