Hi, Robert,
What's the motivation for allowing subscripted variables in local variable
lists? It seems to me that it opens up a bag of worms with no strong
motivation.

Here are some issues:
lis: [5,6,7]$
lambda([a,a[1]], makelist(a[i],i,1,3))(lis,25) => [5,6,7], [25,6,7],
or aliasing error?
lambda([q,a], q[1])('a,[5,6]) => 5 (current behavior)
lambda([q,a[1]], q[1])('a,lis) => ?
foo[x] := if x<0 then 0 else foo[x-1]+1$
[ lambda([foo[1]], foo[2] )(5), foo[1], foo[2] ] => [ 6, 1, 6 ] ???!!!
[ lambda([q], q[1]: 3)(lis), lis ] => [ 3, [3,6,7] ] (current
behavior, OK)
lambda([q,q[1]], q[1]:1, q) (lis,99) => [5,6,7]? or [1,6,7]?
