Equivalent to scan? #10

Closed MiloszKrajewski closed 9 years ago

MiloszKrajewski commented 9 years ago

I could not find scan, am I missing some other method which does the same but has different name? I would like to implement let's say, running sum, so for input stream { 1; 2; 3; 4; 5 } it emits { 1; 3; 6; 10; 15 }. So it needs to behave both like map (emitting data as it arrives) and fold (passing state)

Yes, scan is a very important combinator that we are currently missing. I will implemented it as soon as possible.
