That's certainly an option... if I get what you mean, instead of a list of
ranges (start/finish pairs), you get two index sets (one for the min and
one for the max). The question then, is what's a convenient way to write
an index set. How about:

A( index_set(2)(1)(5), index_set(4)(2)(1) )
        ^                 ^
       min               max

where this index_set thing uses operator() recursively to accumulate the
index set.

Since this is basically equivalent to the other method, it wouldn't be too
hard to supply both.
