'status' and 'raiseStatus' (and 'redirect') overlap in functionality about scotty HOT 5 OPEN

if you raiseStatus 308 "/foo/bar" you get redirected.

No please don't do this, because "/foo/bar" is not a response body but a location header (I assume that's your intent). It would be very strange to change the semantics of the second argument depending on the value of the status code.

I think the right direction is to get rid of raiseStatus altogether, and encourage users to use either finish or a user-defined exception

one problem with deprecating raiseStatus is that we use it internally when a request body is too large.

IMO calling raiseStatus from scotty should be avoided because it makes it harder to customise the response. How about making ScottyException more semantic, providing a default handler in place of statusErrorHandler? For example it could be data ScottyException = RequestTooLarge | MalformedJSON |...

This way, by setting defaultHandlers users are able to customise the handling of these exceptions

Sure. I'll submit a PR in the coming days
