believe me i read the posts (more than a few times) - especially yours
in fact and am very appreciative. however, it takes me a while to
understand what's going on - even to connect similar ideas together. i
certainly don't mind long posts either, but i am still having
difficulties putting the ideas together. i tend to be a bit slow anyway
and keep thinking in python terms.
i intend to respond once i understand the ideas better. for instance,
what you wrote here made sense to me:
let readBlahTxt = readFile "blah.txt"
content <- readBlahTxt
This should show the difference more clearly.
however, i still can't quite connect it to the idea of what it has to
do with getting monad data out of a monad and into the pure realm.
late last night, though, i was able to do so, but it took while.

agreed and i apologize. my problem is that i don't even see that it is
the same question. as you have pointed out once before, "You're still
thinking way too complicated."
i think what happens is i keep trying different things over and over
again. that affects my thinking no doubt. i should likely think more
and try less.

this wasn't clear to me till now even though i had read your continuing
exchange with kyle and the example both of you were discussing
regarding >>= (and i had read up on the operator and even tried it).

i would very much like to see yours.
> I agree with Brent
i think brent's delightful blog post describes my present dilemmas ...
except i haven't quite gotten to the point of being able to say "monads
are burritos" ... so i think there is likely still hope for me. ;)
