> By the way seriously: how do you debug Haskell programs? Mostly seriously: I don't. If the programme doesn't work the way I intended it, I rewrite bits in a simpler fashion until I understand it well enough and it works. For the sort of programme you were asking for, breaking things up until they are small enough that one can understand the individual parts completely (as I did in the solution I posted) and then composing them together really is the best approach. If you need to debug a programme that simple, what it's telling you is that you've written it the wrong way! -- Jón Fairbairn

[discussion of the merits of lazy, eager, macros snipped] The idea isn't to blunder into a language looking for evidence to support a bunch of preconceived misconceptions. the idea is to understand why things are the way they are. macros have advantages and disadvantages. graham lists them in that same chapter. understanding those lets you choose the right tool for the job. that's why it's a good book. if you're not interested in choosing the right tool, but only in proving that something is "better" or "worse" than something else, then why waste time reading books? the world is complex and the more you understand the less certain things become. if you prefer simple black and white then it's better not to learn... (maybe i should add that i don't use lisp; that normally i find it's lisp users who are annoyingly dismissive of other languages; that i, too, have criticised things before understanding them at times; also it's monday morning and i'm still on my first cup of coffee) -- andrew cooke

If you put up a video about monads, the comments are fantastic: * "Anyone figure out what this moron is jabbering about yet?" * "Worst video on the internets" * "Shoot the mathematicians" and my personal favourite: * "What is a Monad? A miserable pile of functions."
A puzzlingly named, exceedingly technical device introduced to structure the denotational semantics has by now achieved cult status. It has been married to effects -- more than once. It is compulsively looked for in all manner of things, including burritos. At least two ICFP papers brought it up without a rhyme or reason (or understanding), as the authors later admitted. I am talking about monads.
