----------------------------------------
There seems to be issue in parsing with white space:

The code below works:

~~~ruby
proc_issue (Proc.new { |n|
  "Do something"
})
~~~

That code causing parsing error (removing white space makes it working `proc_issue` (`Proc`..)

~~~ruby
proc_issue (Proc.new do |n|
  "Do something"
end)
~~~
