[ruby-core:99978] [Ruby master Bug#15409] OpenStruct error when attribute is called 'method'

Issue #15409 has been updated by byroot (Jean Boussier).


> The only complicating factor is json has a dependency on ostruct. JSON::GenericObject inherits from OpenStruct

It is of very questionable usefulness though, so it could probably be deprecated at the same time, or make lazy loaded and make it try to load `ostruct`.

Bug #15409: OpenStruct error when attribute is called 'method'
https://bugs.ruby-lang.org/issues/15409#change-87516

* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
The following error is shown when you try to access an OpenStruct with a property called method:

`method': wrong number of arguments (given 0, expected 1) (ArgumentError)

To replicate:

~~~ ruby
require 'ostruct'
o = OpenStruct.new({ method: 'get' })
o.method
~~~


The expected behavior should be to return 'get'
