Alexander, In my post (excuses for my dyslexia) I try to demonstrate that the codomain (m a), from the point of view of C. Theory, can be seen as 'a' plus, optionally, some additional element, so a monadic morphism (a - m a) is part of a endofunctor in (m a - m a) When considering the

[Haskell-cafe] Monospace code in Haddock

Is it possible to use inlined monospaced font in Haddock that does *not* replace and to links and does *not* link to Haskell functions (like @ and ' and and ` do)? Like: -- | This function gives you @span a1=v1str/span@ something :: String The @ above of course makes everything unreadable

When you write: -- | This function returns the string @hello@ and you have a function called hello in scope, haddock will hyperlink the the above hello to that function, which is confusing if your monospace string has actually nothing to do with that function. In other words: Haddock always

You are right, if I escape as you describe, it works. However, all the makes it quite hard to read in code, and as people often read the code when dealing with Haskell, I will probably stick with the non-inline approach. That also gives a nice blue highlighting in haddocks in addition to the
