Yes, I think that the current consensus is for the solution introduced 
by Doug (I clearly remember a message from Benjamin, for instance). 
Therefore, Chris, since we need to standardize to 20 parameters (and 
*definitely* avoid those workarounds in mu_iterate.h) we can either 
regenerate the tuple header using your C program, or (preferably ;) 
introduce the same solution for tuple too. Of course it's up to you, but 
we don't have much time to decide since we *really* hope to check-in the 
remaining parts of "3 function objects" in time for 4.0, also allowing 
for some testing...

Generally, Doug, your contribution is certainly Ok with me and very 
welcome, thanks!

Paolo.
