As some articles say, do notation is expand to (>>) and (>>=) when
being compiled.
So I want to know the details. Like:
main = do
a <- getArgs
b <- getLine
myFunc1 (head a) b
myFunc2 b (head a)
I cannot figure out what is the (>>) and (>>=) way of this.
If you are on FreeNode IRC, you can ask lambdabot to @undo such
expressions (would need to use braces and semicolons instead of layout
though).
main = getArgs >>=
\a -> getLine >>=
\b -> myFunc1 (head a) b >>
myFunc2 b (head a)
