Hi Bulat,
Do you have examples of usefulness your sugar for monads besides the one?
Since "do" sugar is notation for general monadic programming, I wouldn't
want to see it made more complex for the sake of just one monad.

Hello haskell-prime,
as we know, the following code
action x y >>= \v -> do
can be shortened to following
v <- action x y
but there is one more very popular 'do' pattern, with a 'do' block passed as a parameter:
for list $ \element -> do ...
or
bracket createDialog destroyDialog $ \dialog -> do ...
what about adding one more 'do' sugar that will allow to move variable name to the left, such as
for element in list do or with dialog in bracket createDialog destroyDialog do
or just
element <-- for list do dialog <-- bracket createDialog destroyDialog do
?
