With out this patch loading the a the page in the below example results in the

following error:

```
getByETest.hs: user error (Pattern match failure in do expression at src/Graphics/UI/Threepenny/Core.hs:143:5-15)
```

The same problem exists with all getElement functions as far as I can tell.

example code that demoenstrates this problem can be found at the following paste

This fixes an error found on
os: 10.8.5
ghc: 7.6.3

I have also posted to SO for further insight it does not seem like I should expect a difference between pattern matching in do notation vs let.
