Apply a function to each element of a Stream, lazily

Map a function over all values in the map.

map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]

map f s is the set obtained by applying f to each element of s. It's worth noting that the size of the result may be smaller if, for some (x,y), x /= y && f x == f y

Map a function f over all the ModSummaries. To preserve invariants f can't change the isBoot status.

map a function over the nodes of a Block

A strict mapBlock

map over a block, with different functions to apply to first nodes, middle nodes and last nodes respectively. The map is strict.

Maps over all nodes in a graph.

Function mapGraphBlocks enables a change of representation of blocks, nodes, or both. It lifts a polymorphic block transform into a polymorphic graph transform. When the block representation stabilizes, a similar function should be provided for blocks.
