Feature #14498

Updated by Hanmac (Hans Mackowiak) about 3 years ago

Hello! 

 I was creating a list of class instances via `some_list.map { |e| SomeClass.new(e) }` and wondered if there's a `Class#to_proc` to make possible doing `some_list.map(&SomeClass)`. 
 Well, there is not. 

 Basically, this is what I suggest: 

 ```ruby ``` 
 class Class 
   def to_proc 
     proc { |*args| self.new(*args) } 
   end 
 end 

 class Dog 
   attr_reader :name 

   def initialize(name) 
     @name = name 
   end 
 end 

 names = %w[Lucky Pluto Balto] 
 names.map(&Dog) # map names to dogs 
 ```
