How about moving the messages for compiler to an additional file?
My motivation is that we often face a trade-off between
aesthetical(elegant code) and practical(efficient code).
Like pragmas and strictness annotations, I often feel they make the
source code ugly.
They don't affect the semantics
specifically I am concerned about ByteString and underlying nodes .. ???
