Hi,
I am not sure just how you wanted to have 'array/initial work, but at first
thought you would probably need to redefine 'array or create your own
function. On the other hand it looked like you just might want this:
a: array [3 2] [10 60 10]
But you did say *increment* so I am not sure. ;-) If you literally did want
an incremented value, then yes you will probably need to use loops. But you
might want to create your own generic function to do it if you like
incremented arrays. ;-)
I thought that I had some light to shed on *contexts* but it appears that my
light has faded. ;-( I would play with different combinations of 'compose
and 'bind to try to find what I was looking for. I have done some bind
stuff, but ended up writing my own version of bind to get what I was looking
for...
