I'm running GHC version 7.8.3 on Windows 7.

Ok, this is not about fancy code snippets. I'm just trying not be a noob here and actually compile something in a way that vaguely resembles the structure of side-effect languages.

I have the following code:

```
main =
do {
let x = [0..10];
print x
}
```

I've learned here, that the keyword do is a fancy syntactic sugar for fancy monadic expressions. When I try to compile it, I get the following error:

```
main.hs:4:1: parse error on input 'print'
```

And I've learned in this other question, that tabs in Haskell are evil, so I've tried to omit them:

```
main =
do {
let x = [0..10];
print x
}
```

And I've failed miserably, because the parse error persists.

I've also learned here, that print is a syntactic sugar for the fancy equivalent:

```
main =
do {
let x = [0..10];
putStrLn $ show x
}
```

But then I get this error instead:

```
main.hs:4:9: parse error on input 'putStrLn'
```

Trying to face my despair, I've tried to omit the let keyword, after reading this answer:

```
main =
do {
x = [0..10];
print x
}
```

And then I get:

```
main.hs:4:1: parse error on input '='
```

And in a final useless attempt, I've even tried to omit the ';' like this:

```
main =
do {
let x = [0..10]
print x
}
```

And got:

```
main.hs:4:1: parse error on input 'print'
```

So,

**How** to properly use monadic expressions in Haskell without getting parse errors? Is there any hope?

Answer:

```
main = do let x = [0..10]
print x
```

works for me

and so does

```
main = do { let x = [0..10]
in print x }
```

I think you're trying to mix some different syntax options up.
