Anybody see any problem with that #read: implementation to be able to count magma things?
Hi Sebastian, are you wanting to tally the number of dates for each *unique* date, a la classic "control-break" reporting?
Or, are you simply wanting all elements in a MagmaCollection sorted by date, in which case there is MagmaCollection>>#read:..?
But I see you want to extend #read: on MagmaCollectionReader, so I'm not sure what that is for..
