Subject: [ruby-core:116848] [Ruby master Feature#11446] Possible work around for the requirement to supplying arguments like this: .map(&:method, <arguments>)

Issue #11446 has been updated by artemb (Artem Borodkin).




Are there any proposal issues regarding the addition of argument and block support for the ```.each(&:method, args) do; end``` syntax?

It seems quite feasible to support it natively.

``` ruby
module Enumerable
  def each_call(method, *args,  &) = each { _1.send method, *args, & }
  def map_call!(method, *args,  &) = map! { _1.send method, *args, & }
  # ...
end

# [1,2].map! &:+, 1
[1,2].map_call! :+, 1

# [].each &:instance_eval do
%w[1 2].each_call :instance_eval do
  @v = 1
end
```

Any chance this [work around](http://stackoverflow.com/questions/23695653/can-you-supply-arguments-to-the-mapmethod-syntax-in-ruby/23711606#23711606) can be considered to be part of the language. Seems to be a pretty neat.

NB: Matz seems to be interested in having this added: Check his [tweet](https://twitter.com/yukihiro_matz/status/632016695016620033).
