Bug #14021
closedBlock parsing with arguments
Description
It appears that between 2.4.1 and 2.4.2, something changed with method argument parsing:
$ cat test.rb
#!/usr/bin/env ruby
def test(num)
p num
yield
end
test 5 { puts 'hello world' }
$ rbenv shell 2.4.1
$ ruby -v
ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin15]
$ ruby test.rb
5
hello world
$ rbenv shell 2.4.2
$ ruby -v
ruby 2.4.2p198 (2017-09-14 revision 59899) [x86_64-darwin15]
$ ruby test.rb
test.rb:8: syntax error, unexpected '{', expecting end-of-input
test 5 { puts 'hello world' }
^
I'm actually fine with this change, but it didn't used to emit a warning and it seems odd that a patch release would break this behavior.
