It's not lazy, it returns iterator. There is a difference, you can't slice or index its result anymore. Compare to Clojure or Haskell map, which are truly lazy.

No it won't, unless you `tee` an iterator first.

It's easy cause it's familiar. But it's not simple. This excellent talk by Rich Hickey explains the difference http://www.infoq.com/presentations/Simple-Made-Easy

If core is small then such language should provide a way to extend it outside. Like macros.

Just zip(seq, seq[1:]) Won't work with iterator though.

It doesn't need direct port. But it can take advantage borrowing ideas or library design principles.

The first part of a post is mere reasoning showing how I got to the actual interface I use. @decorator works with `call` not with `func, args, *kwargs`.

funcy doesn't preserve function signature. The only way for now to do this is to use exec, e.g. compile code from source or AST, which I choose to avoid.

You will still need a wrapper function and update it's metadata. Which is even more boilerplate. Or you can hide that in base Decorator class, but then we'll back to another layer of abstraction. So it's either more boilerpla

This handles decorators with arguments and makes a general case of passing same arguments to function as to wrapper less cluttered.

This looks like even more boilerplate.

You can pass flags and compiled regular expression. Pattern with named captures causes re_find to return dict. You won't get entire match if you have several captures, but you can add a pair of parentheses around your regexp to circumv

re_find returns tuple of all captures if there are more than one. See parse ini example

Oh, I probably should spend some time clarifying the docs. But basically it just helps avoiding nesting functions, a common boilerplate when writing decorators.

No, @decorator takes care of it - http://funcy.readthedocs.org/en/latest/decorators.html

There is a price for new vocabulary involved, which is some learning curve. By the way, first piece of code can become much more hairy with time.

Yes, that decisions look dirty and dubious, but using funcy for several months, I've come to that practicality and convenience is worth it. Some of itertools things are just reexports and builtins are extended purely - so that they behave t

Yes, where() doesn't handle that case, but it makes its interface more smooth for more common case of string keys. That was a deliberate choice.

Predicate in some() is optional. A test for boolean truth is used in that case. So, first example is the same as: some(bool, [0, '', -1, None, 2])

Sorry, if this is a dump question, but how I can add some package and then require it in playground? I'm trying to (require 'http.async.client)
