So is that the language's fault (because of what you get) or the
editor's fault (because of what you see)?
I'm guessing that what you see and what you get have *never* been
identical for you, but you didn't care much, because they were
Now, with Haskell, that difference has become significant. And it's a
(perhaps minor) problem. What is the cause of the problem?
1) Haskell makes the difference between what you see and what you get
significant, it should not be that way
2) Your editor does not let you see what you're going to get, it
should not be that way
If you see the source of the problem as 1, you will likely choose the
braces-semicolon route, or unfortunately (for you ;) ) not use
Haskell. If you see it as 2, you will decide to reconfigure the
editor you use for programming so that what you see *is* what you

And in exchange, two old problems suddenly went away: syntax errors
due to incorrect bracketing or termination/separation, and formatting
that was *not* significant (code that was formatted as if it did one
thing but actually did another).
