I would suggest to use Python or some other mainstream language instead of Haskell in example to contrast to Idris. People who know Haskell most likely be already familiar with dependent types and for people not familiar with Haskell syntax could be confusing (as some comments indicate).

[cantankerous]

Many mainstream languages like Python don't even have a syntactic notion of types. The best you could really do is say that Idris would get you some typing reification that you might do in those languages at no cost, but it would seriously sell short the power of dependent types like you see in Idris.
