+Interpretation

+simpl : |<a>| -> |<a>|
+simpl : (a |->| b) -> (a |->| b)
+
+simpl simplifies and optimizes a task or operation.
+
+linearize : |<a>| -> (0 -> a)
+linearize : (a |->| b) -> (a -> b)
+
+linearize interprets a task or operation to run sequentially on a single node.
+
+localize : |<a>| -> (0 -> a)
+localize : (a |->| b) -> (a -> b)
+
+localize interprets a task or operation to run in parallel on a single node.
+
+distribute : |<a>| -> (ResourceInfo -> a)
+distribute : (a |->| b) -> (ResourceInfo * a -> b)
+
+distribute interprets a task or operation to run in parallel distributed among
+several nodes.
