I see. Please remove the test if the test is unnecessary.

A little sugar on Symbol does look really nice: https://gist.github.com/havenwood/d305b42f5b542e9de1eaa8e56ba6bdd7#file-compose_procs-rb-L32-L45
----------------------------------------
Feature #6284: Add composition for procs
https://bugs.ruby-lang.org/issues/6284#change-73383
* Author: pabloh (Pablo Herrero)
* Status: Open
* Priority: Normal
* Assignee: nobu (Nobuyoshi Nakada)
* Target version:
----------------------------------------
It would be nice to be able to compose procs like functions in functional programming languages:
```ruby
to_camel = :capitalize.to_proc
add_header = ->val {"Title: " + val}
format_as_title = add_header << to_camel << :strip
```
instead of:
```ruby
format_as_title = lambda {|val| "Title: " + val.strip.capitalize }
```
It's pretty easy to implement in pure ruby:
```ruby
class Proc
def << block
proc { |*args| self.call( block.to_proc.call(*args) ) }
end
end
```
