lookup(task_name, initial_scope=nil)

public

Lookup a task, using scope and the scope hints in the task name. This method performs straight lookups without trying to synthesize file tasks or rules. Special scope names (e.g. ‘^’) are recognized. If no scope argument is supplied, use the current scope. Return nil if the task cannot be found.
