Some more daydreaming:

If tuples would be a language feature, instead of just a library, I'd
really like to see that parameter lists of functions would be tuples.
Much of the code repetition in template libraries originate from the
need to provide different versions of the same code for similar
functions that have different number of parameters (see. binders,
lambda, function, ...)
Would the argument list be a tuple, a single template
could cover all function types.

Tuples are a proposed addition to Eiffel, and paramter lists
are tuples are in Eiffel.
