What I Wish I Knew When Learning Haskell

Hey, I didn't say one was worse or better but merely suggested some arguments as to why one might dislike that signature.

Clearly, as you demonstrate, the syntax described can be shortened—but it wasn't.

And by the definition being tied to the implementation I mean that it's not possible to write, e.g.

    foo :: Type1
    bar :: Type2

    foo = ...
    bar = ...

pekk asked what was wrong with the syntax.

I didn't change the syntax in any way.

'k.

Is that actually used? Global type inference I could see, but that seems odder.

Fair enough. I conflated syntax with convention.

It is used quite frequently, actually, e.g. in describing type classes.
