Subject: [ruby-core:52968] [ruby-trunk - Feature #6841] Shorthand for Assigning Return Value of Method to Self


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


=begin
If there are concerns about using an identifier after ".=", then perhaps a symbol could be used instead:

(({obj.foo.bar.baz .= :to_i}))

That would be somewhat consistant with the alternate block syntax (not sure what it's called):

(({['a', 'b', 'c'].each &:upcase!}))
=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?
