slurp_remove :: FileName -> Slurpy -> Maybe Slurpy

A variant of get_slurp_context that allows for replacing the child slurpy by a list of slurpies. The result of the update function will always be a singleton list unless the child slurpy was at the top level. Currently unused. get_slurp_context_list :: FileName -> Slurpy -> Maybe ([Slurpy] -> [Slurpy], Slurpy) get_slurp_context_list = get_slurp_context_generic return id

It is important to be able to readily modify a slurpy.
