With this change, code like this works:

puts "hello"
      .upcase
      .reverse
      .slice(0)   #  => prints "O"

I'm not sure what "experimental" means when coming from Matz, but I 
think this is a very nice new feature.

I haven't looked at Matz's code but I assume that the rule is that a 
newline is not a statement terminator if the first non-space character 
on the next line is a dot.
