There is a way now, mentioned in #12113. I'm not sure whether it is good idea to use it, though.

#send(:format) to an OpenStruct with a field named :format raises an ArgumentError in Ruby 2.3.0:

~~~
OpenStruct.new(format: :bar).send :format
ArgumentError: too few arguments
~~~

It works as expected in ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-linux] and with any other method name I tried:

~~~
OpenStruct.new(f: :bar).send :f
=> :bar
~~~

String or Symbol in the OpenStruct definition and as argument of #send make no difference.
