Sadly. It looks that code basing on such a spec isn't written in a good manner =\

Feature #6672: Calling #() without dot before braces

=begin
It looks odd to call Proc/Method `(({pr}))` using `(({pr.(*args)}))` or `(({pr[*args]}))` syntax. Why not to use (({pr(*args)})) syntax? In such a case methods(procs) would become nearer to first-class object and calls are more standardized such that there's much less difference between method call and call of (({#call})) method

So I suggest syntax `(({x.(*args,&block)}))` alias to `(({x(*args,&block)}))`
It will make it possible to transparently redefine any method in a scope like this:
  class String
    def my_meth(direction)
      index = method :rindex  if direction == 'RtoL'
  #   ... lots of code that uses #index method
    end

    def my_second_meth
      upcase = method :downcase  # we decided to try what if we change all upcases to downcases in this method and added such a line
  # lots of code using upcase() method
      upcase()  # it's sad that it's impossible not to use brackets at all, but this'd be ambiguous
    end
  end

Also I wrote about syntax like (({:meth.(*args)})) which creates a proxy-object having to_proc method - so that it's possible to write (({[1,2,3].map &:to_s.(2)}))  --  now no dot in such syntax

Also it'd be possible to implement some object with syntax like `(({obj(args1)(args2)}))` - obj has method (({#call})) that returns object that also has method (({#call})) and they are both called.
It can be in such a way: (({method(:index)('z')}))

One problem is that it can behave differently from current behavior in case that method have the same name as a local-variable. Now it works in such a way:
  p='var';
  print p #=> 'var'  ## works as local variable
  p('hi') #=> 'hi'   ## works as method call

I don't know if it's a spec, I suppose that one mustn't use both variable and method at the same place. So even it's a spec it can be revised in future versions of ruby so that new behaviour would be like that:
  p='var';
  print p #=> 'var'  ## works as local variable
  p('hi') #=> undefined method `call` for 'var':String
