Apply a function to each element of a Stream, lazily

map f xs is the list obtained by applying f to each element of xs, i.e.,

map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
map f [x1, x2, ...] == [f x1, f x2, ...]

>>> map (+1) [1, 2, 3]
[2,3,4]

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.
