Bug #5540

ruby -v:ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0] Backport:


The following code parses and runs correctly under 1.9.2-p290 but causes a syntax error under 1.9.3-p0:

def test(foo, &block); end
test 'hello', do; end


#1 Updated by Joshua Ballanco about 4 years ago

This was introduced by r32235:

* parse.y: comma at the end of line is no longer allowed.
  A patch from Yukihiro Matsumoto  <matz AT ruby-lang.org>.
  (fixed #3456).

Is it intended that the above syntax should no longer be valid in Ruby 1.9.3?

Syntax error is intentional. It was caused by a 1.9.2 bug.
