Documentation
Used at the type level to indicate a "closed" structure which supports control transfer only through the use of named labels---no "fallthrough" is permitted. The number of control-flow edges is unconstrained.
Used at the type level to indicate an "open" structure with a unique, unnamed control-flow edge flowing in or out. Fallthrough and concatenation are permitted at an open point.
data Block n e x where Source #
A sequence of nodes. May be any of four shapes (OO, OC, CO, CC). Open at the entry means single entry, mutatis mutandis for exit. A closedclosed block is a basic/ block and can't be extended further. Clients should avoid manipulating blocks and should stick to either nodes or graphs.

Fold a function over every node in a block, forward or backward. The fold function must be polymorphic in the shape of the nodes.
isEmptyBlock :: Block n e x -> Bool Source #
mapBlock :: (forall e x. n e x -> n' e x) -> Block n e x -> Block n' e x Source #
map a function over the nodes of a Block
