maybe make a version of filter/map that lets you also pass in a block type and in/out conversion? basically something that lets you specify "yeah, my operation block should have this signature: returns int, takes in an int" and then you also pass in the block that does that conversion? then, you could provide default values for "int/int" or "float/float"?
