Subject: [ruby-core:54753] [ruby-trunk - Feature #8361] Alternative syntax for block parameter


Issue #8361 has been updated by alexeymuranov (Alexey Muranov).


=begin
You are right, there is a problem.  It is similar to the problem with hashes:

  def f(h); end
  f {1=>2}
  # => SyntaxError: unexpected =>, expecting '}'

I will think more about it.

Feature #8361: Alternative syntax for block parameter

=begin
I propose an alternative syntax for block parameters:

  p = lambda [x] {
    # do whatever you like with x here, but be sure to return the result
  }

instead of

  p = lambda { |x|
    # ...
  }

This would be consistent with the syntax of procedure call: (({p[a]})).

Also, compare:

  a_bunch.each [element] do
    # ...
  end

with:

  a_bunch.each do |element|
    # ...
  end
