Bug #14023
SyntaxError on array argument and block
Description
$ RBENV_VERSION=2.4.2 ruby -v ruby 2.4.2p198 (2017-09-14 revision 59899) [x86_64-darwin16] $ RBENV_VERSION=2.4.2 ruby -c -e 'a [] {}' Syntax OK $ RBENV_VERSION=2.5.0-preview1 ruby -v ruby 2.5.0preview1 (2017-10-10 trunk 60153) [x86_64-darwin16] $ RBENV_VERSION=2.5.0-preview1 ruby -c -e 'a [] {}' -e:1: syntax error, unexpected '{', expecting end-of-input a [] {} ^
Is this intentional? This causes syntax error on https://github.com/plataformatec/devise/blob/v4.2.0/app/controllers/devise/sessions_controller.rb#L5.

Matz's intention is very clear that this kind of expression shall render syntax errors.
