Yes.

|1.  puts (a+b), c    works - no warning is generated
|2.  puts(a+b), c     fails
|3.  puts(a+b, c)     works - no warning

|5.  puts (a+b)       works - no warning
|6.  puts(a+b)        works - no warning

Hmm, I had extended syntax rules little by little, so that the
argument warning behavior might be inconsistent.  I will revisit it
soon.
