[clean-list] Optimising Recursive Functions Yielding Multiple Results in Tuples?

It is implemented, but not enabled, because there are still a few
small bugs and it has not been tested very well yet.

You should download Clean 2.0 and the source code of Clean 2.0. In the
file settings.c in the folder backendC, change the boolean
OptimizeLazyTupleRecursion from False to True. Then rebuild the backend.dll
using the files in the backendC folder. If you use the CodeWarrior 6
C compiler, you can use the backend.mcp project.
Now use this backend.dll instead, by replacing the backend.dll file in
the folder containg the file CleanCompiler200.exe.
