[ruby-core:47062] [ruby-trunk - Feature #6841] Shorthand for Assigning Return Value of Method to Self

Issue #6841 has been updated by kstephens (Kurt  Stephens).


I like the idea, iff:

  obj.foo.bar.baz .= to_i

behaves as:

  begin
    temp = obj.foo.bar
    temp.baz = temp.baz.to_i
  end

=begin
Quite often in Ruby, I find myself doing something like: (({my_var[:foo][:bar] = my_var[:foo][:bar].to_i})) or (({obj.foo.bar = obj.foo.bar.to_i})). Realising this, I thought of what would be a fairly nice shorthand syntax for this, which could be: (({my_var[:foo][:bar] .= to_i})). How this works should be pretty self-explanatory. The (({.=})) operator works exactly like any other assignment operator of this nature.

Would be nice to see this in Ruby 2.0. Wondering what others think of this?
