How do I get a char from this?
Is it possible to show an alertview with a textbox inside like the AppStore app.
It asks for password in such a dialog.

I want to do something in Haskell that looks like this:
main1 = do s <- getLine if s == "foo" then putStr "You entered foo"
Obviously this isn’t legal since there’s no
else. One alternative I’ve thought of:
So if a language provides higher order procedure then I can have procedure that returns procedure. Something like:
(define (Proc a b c) (lambda (x) ( #| method body here in terms of a b c and x |# )))
To create new procedure, I would just do something like:
(define ProcA (Proc a1 b1 c1)) ; Would create ProcA that has 1 argument
Similar task could be done in a language which does not support higher order procedure by defining
Proc that takes 4 instead of 3 arguments and calling this procedure to define
