This may be confusing, because if the user expects that missing values will 
be covered by the "default=" attribute, then this behaviour will be 
counterintuitive.

This is what I would expect if I am combining 2 variables, and one of the 
does not have the same number of elements than the other.

Guess, we could make this more complex, and specified something like:

$foo default=$foo:LAST

and get the behaviour in the first part, but this can easily get out of 
hand, so I am not too keen about that.

Just for pure speculation, one can also set up things so instead of a simple 
one to one correspondence between the lists, there is a combinatirial 
relation:

red small
red medium
red large
red x-large
blue small
blue medium
blue large
blue x-large

Now that may be interesting.
