Noob here. Im not sure if every function is supposed to be curried (but thats the feeling I got).
If that is indeed the case then how come
(,) 1
throws an error? Shouldn't it return a function that when applied to one more value gives a tuple?

Both of those can be true.
λ> let f = (,) 1 in f 2
(1,2)
But since functions have no Show instance, just typing (,) 1 does throw an error:
λ> (,) 1
<interactive>:4:1: error:
• No instance for (Show (b0 -> (Integer, b0)))
arising from a use of ‘print’
(maybe you haven't applied a function to enough arguments?)
• In a stmt of an interactive GHCi command: print it
