Subject: [ruby-core:53947] [ruby-trunk - Feature #6841] Shorthand for Assigning Return Value of Method to Self


Issue #6841 has been updated by wardrop (Tom Wardrop).


=begin
(({Regarding obj.foo.bar.baz = .to_i})) syntax, with the dot prefix on the ((|to_i|)), another proposal has been made further down the discussion for issue #8191. The idea is that an expression beginning with a dot could be an inferred method call on the result of the last expression.

Just consider that before using the dot prefix syntax for anything else.

=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?
