Re: [Haskell-cafe] Disable echo in POSIX terminal

Pointless frobbing but is there any issue with setting the echo to False when it is already False? Otherwise not checking seems to both simpler and quicker (not that performance matters), i.e. getpasswd h = do wasEnabled <- hGetEcho h hSetEcho h False str <- hGetLine h hSetEcho wasEnabled return str

Should one enclose this in 'bracket'?
