Write a monadic operation that enables you to retrieve the last-saved remainder, at any arbitrary later point in the computation. For example, you want to be able to calculate expressions like this:
- (((some_long_computation / 12) + 5) - most_recent_remainder) * 2 - same_most_recent_remainder +1
+ (((some_long_computation / 12) + 5) - most_recent_remainder) * 2 - same_most_recent_remainder + 1
-The remainder here is retrieved later than (and in addition to) the division it's the remainder of. It's also retrieved more than once. Suppose a given remainder remains retrievable until the next division is performed.
+ The remainder here is retrieved later than (and in addition to) the division it's the remainder of. It's also retrieved more than once. Suppose a given remainder remains retrievable until the next division is performed.
