There's no easy way to list all of the tasks in a recipe, you can either
look at __BBTASKS (internal variable, shouldn't be used) or iterate all
items in the datastore looking for variables with the 'task' flag set
(which is slow).
Solve this problem by adding a bb.build.listtasks() function that
returns an immutable copy of the __BBTASSK variable.
