Of Monads and Men

Just found the 25, It's very similar to my 26 but slightly less interesting

I had the patterns the other way around

Yeah, I think just found your 26 byte answer

Actually I think my 30 byte approach was also kind of interesting: Try it online!

Couldn't find any solution

@Laikoni what the heck

How can you use let there??

@Laikoni Interestingly the restricted import doesn't let you write [False..True] directly

I saw the fact that an empty let works as catch-all pattern guard first in an answer by H.PWiz.

Nope

I just found out that you can use `let` instead of `otherwise` in a guard.

fac n|n==0=1|let=n*fac(n-1)

Is it in the tips?

No, but it would only be useful for restricted source

I know, but I wouldn't start a separate Tips for restricted source challenges in Haskell :)

xnor

i've got 23

@Potato44 please consider adding it to the tips for golfing in Haskell!

@H.PWiz It does, it's just that False.. appears to be parsed as one token. Inserting a spaces fixes the issue.

Yeah, just noticed now...

(also works in things like [0|_<-[0..5],let])

@xnor So back to the drawing board it is ...

1 hour later…

@Laikoni Finally found it. Now for the other logical gates ...
