Although terse, the subject really says it all.
If i've a partial function, like a parser, what is considered good
style for a library. The tradeoffs that I can see are that Maybe is a
binary operation, while Error can communicate more information in the
type of the error case.
Is there some way to defer the error handling Monad to the calling context?
