When I execute code below:

$ ./ruby -e '-> { true }.curry.call(&:to_s)'

I create a patch for fix and test. I hope for your help :)

And logs:

[trunk][~/devel/ruby]$ ./ruby -e 'proc { true }.curry.call(&:to_s)'                                                                                           rbenv:2.4.0-preview1
