Hi! I&#39;m new to Haskell.  Following someone&#39;s notes, I was doing this &quot;doubleMe x = x + x&quot;.  I did this two days ago and it worked.  But I try to do it today, I got an error &quot;parse error on input &#39;=&#39; &quot;,<div>
This is rather inconsistent and should not happen in a computer compiler (i.e. day one works, day second not work) This comes up in both cases: loading a .hs file and interactively.  Can anyone tell me what I did wrong?  This happened to both my Win XP and my Ubuntu 10.10 PC.  Thank you very much.  Cheers.  Simon.</div>
