• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.4.2p198 (2017-09-14 revision 59899) [x86_64-darwin16]

# ruby 2.4.1
p :bar do end # => :bar
p :bar {} # => :bar

# ruby 2.4.2
p :bar do end # => :bar
p :bar {} # => SyntaxError: syntax error, unexpected '{', expecting end-of-input

In the wild this will mainly affect rspec code:

let :foo { bar }
