Feature #14498
Updated by Nondv (Dmitry Non) almost 7 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:
```
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
```
