Last night I thought writing a simple arithmetic calculator in Haskell would
be pretty cool. Parsec makes it so easy to parse simple arithmetic
expressions. Coming from a Ruby/C# background, that would really impress me
- that kind of parsing isn't easy!

Not sure how hard it would be - but extending the calculator to different
units or to symbolic expressions (i.e. simple variable assignments) would be
impressive.

Sorry I don't have any code to provide :)
