Subject: [ruby-core:47047] [ruby-trunk - Feature #6841] Shorthand for Assigning Return Value of Method to Self


Issue #6841 has been updated by trans (Thomas Sawyer).


=begin
Does `.` effectively become a "call dispatch operator" then? Could one write:

  a.send('.', :foo)

I like the idea. But to complete the comparison to other operators, it made me think `.` would be some sort of method.

=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?
