Subject: [ruby-core:55094] [ruby-trunk - Feature #8361] Alternative syntax for block parameter


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


=begin
I do not mind this being closed, i do not see how this can be made consistent with the existing syntax, and probably me reason for suggesting this was not valid, but as a side note, i want to mention that i have just discovered that in Combinatory Logic, when a lambda term from Lambda Calculus is converted to an equivalent combinatorial term, an alternative intermediate notation used sometimes for "(({��x.M}))" is "(({[x].M}))":
((<URL:http://plato.stanford.edu/entries/logic-combinatory/#2.3>)).

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
