Edit Question
Title
Body
I am trying to understand maybe Monad but most of the examples I saw used some language-specific feature. To ensure that I have gotten it conceptually right I thought of writing a generic implementation. Below is what I came up with. Can someone tell if I have gotten it conceptually right? Is there a better way to generalize it? def f(): return 2 def g(): return 4 def h(): return 7 def i(): return None def bind(val, func): if val is None: return None else: return(func()) unit = 0 >>> bind(bind(bind(unit,f),i),h) #Returns nothing >>> bind(bind(bind(unit,f),g),h) #Returns a value >>>7 What if I wanted to add the values from these functions and abort if any of those was NULL; any suggestion?
