Add alias_class_method or class_alias functionality
Hi core team,
First drink a Calpis (カルピス Karupisu) before reading on :-)
Now, my proposal is to add a slight new feature that is mostly one of convenience.
We have two ways to use aliases:
But are similar but not 100% the same.
Now this works all fine and nice.
But how to define a class method? Well, simple:
class Foo; def self.hi; puts 'hi'; end; end; Foo.hi
But how can we make an alias to this class method?
Well, this is ugly - here is one way:
class Foo; class << self; def ho; hi; end;end;end
Is this readable to you?
Using alias would be more readable.
Ok, we can simplify it by using alias:
class Foo; class << self; alias ho hi; end;end
But I don't like the class << self there, just to make
a single class alias.
I thus propose a new method called:
The above could then be rewritte like so perhaps:
class Foo; class_alias :ho, :hi; end # I guess this would be more akin to alias_method
If the name is bad, it could be:
Perhaps. Anyway, the name is not so important, I am sure a good name can be found,
but I wonder if this would be a good feature to add or not.
Thanks for reading!
