Avoid using ILDASM at any costs.

First because the only publicly available API (as far as I can
remember) is the flag that you pass to the Regex engine to compile to

You should avoid reverse engineering their code, because it gives you
less implementation freedom (the only thing you really get to enjoy
when implementing someone else's API) and then you can put your code in
jeopardy in terms of having someone claiming that you copied their code. 

So as a principle, in Mono we avoid using ILdasm to look at their
dissasembled code.
