No need for $. about dollar

[ankurp]

Are you suggesting creating categories like in Objective-C for array, dictionary, etc. types in Swift?

Based on some interest I'm thinking it might be worth creating another project within this repo which would shared functionality and implement extensions for different collection types.

Developer would then have a choice to import a pure functional library like Dollar or import extensions via Cent library.

I think what @eklipse2k8 meant is that we don't need a class to namespace the functions, because they are implicitly namespaced by the framework's module, i.e. "Dollar". So even without having the functions grouped under a class a third party app can call them like Dollar.first([1,2]) (or just first([1,2])) but not $.first([1,2]).

[eklipse2k8]

@nubbel exactly. These are handy functions that you could even make some of them generics, without needing to type $.

@eklipse2k8 and @nubbel I see what you guys mean but to avoid ambiguity and not to pollute the namespace of the class in which it is being used it would be good to have a namespace to reference these functions by. So for example calling a function as Dollar.first imply that it is the library function and not the Swift.first which can also be implemented in the future as part of language update or another first function defined in the class. The compiler sometimes complains with Ambiguous use of 'first' as seen here if there are duplicate function names

I created a new project in the repo that creates extensions using the functional version in this branch https://github.com/ankurp/Dollar.swift/pull/59/files#diff-ca1a7525d799b7ad848ca0362a4dd934R9

So now you can import Cent if you want extension version or import Dollar if you want to import a functional version of the library. I need to add more functions and classes before I merge this.

[nubbel]

I would prefer generic functions over extensions.

[ankurp]

@nubbel That is why I am keeping Dollar a separate project and framework and Cent is just an extension library using the generic functions from Dollar framework to define the extensions.

namespace is very important, just keep use $ and dont pollute global
