Swindling with Platonism

Haskell programs cannot have bugs. This program does as intended. It's your understanding of the program that's wrong!

That previous language was not Lisp! Lisp has always done it this way. Everything you can think of came from Lisp first. Lisp is an ideal that we can only approach.

Every program does exactly has programmed, no matter the language.

Now you are enlightened! Bugs are a result of misunderstanding in all cases. Unless of course somebody introduced them by intention, but even then we can tell that misunderstanding has happened, and that person way say underpaid and held some other grudge.

why there are debuggers for Haskell?

It's not always misunderstanding. It's also oversight.
