I mentioned earlier that I found the GHCI use-case extremely useful (see my root comment after EDIT). But I have an issue with the uses like turning off the typesystem and have the project compile just so that you could feel good about yourself. I don't believe that would help your bottom-line. But, as long as I don't have to work with you or your software, I don't care.
And, large refactoring efforts are necessary in every complex and evolving system, irrespective of your language of choice -- but turning off your type checker or any other static guarantees isn't the way to go. Programming is hard enough even in the presence of type-checking and automated analyses -- why make it even harder? Anyway, I feel like I've made my point enough -- take it or leave it.
