fromSLA :: ArrowList a => s -> SLA s b c -> a b c #

conversion of state list arrows into arbitray other list arrows.

allows running a state list arrow within another arrow:

example:

    ... >>> fromSLA 0 (... setState ... getState ... ) >>> ...

runs a state arrow with initial state 0 (e..g. an Int) within another arrow sequence
