[ruby-core:45673] [ruby-trunk - Feature #6594] Integrated Functor
From:
"rosenfeld (Rodrigo Rosenfeld Rosas)" <rr.rosas@...>

List:
ruby-core #45673
Issue #6594 has been updated by rosenfeld (Rodrigo Rosenfeld Rosas).
@trans I wasn't claiming that it wasn't possible for those interested on the feature to find real-case examples about it. I was just warning you that some people won't want to spend their time trying to find such examples.
In the other hand if you take some time to choose a single example that you find to be a great one that you could write a Ruby code using the current syntax to show how to implement something and then compare to your proposed new syntax it might help getting the interest of others that are not currently interested enough on this feature to just start learning about it from other links. (Wow, I guess I've just written the biggest sentence I've ever written - sorry for that :P )
----------------------------------------
Feature #6594: Integrated Functor
https://bugs.ruby-lang.org/issues/6594#change-27273
Author: trans (Thomas Sawyer)
Status: Open
Priority: Normal
Assignee:
Category: core
Target version: 2.0.0
=begin
I know the developers meeting is coming up so I'd like to get a few ideas I've had sitting in the wings out in the air before then.
One the more useful is the idea of integrating Functors directly into the language. "Functor" is the term I use for "higher-order function".
I blogged about this idea and you can read it here: http://trans.github.com/2011-09-07-ruby-heart-higher-order-functions/
The super short version is this:
def f => op, arg
arg.send(__op__, arg)
end
f + 3 #=> 6
f * 3 #=> 9
Another example:
class String
def file => op, *args
File.send(__op__, self, *args)
end
end
"README.rdoc".file.mtime #=> 2012-06-14 12:34:45 -0400
I'm using `=>` as means of indicating a higher-order function. Of course another syntax could be used if this won't fly. The important thing is the idea of higher-order functions being integrated directly into the language. Doing this without that integration requires the creation of an intermediate object for each call which is very inefficient.
