Here's what the code looks like:
ArrayedCollection >> #do: aBlock
"Iteratively evaluate the one argument block, aBlock using
each element of the receiver, in order.
Fail if aBlock is not a one argument block."
aBlock apply: self from: 1 to: self size.
--------------
BlockContext >> #apply: aCollection from: start to: end
"Evaluate the receiver for each variable slot of aCollection from
start to end. Answer aCollection."
<primitive: VMprBlockContextApplyFromTo>
start to: end do: [:i | self value: (aCollection basicAt: i)].
^aCollection
Later,
Jon
