|Is this true? I've been unable to find any reference to the alleged

It's in fact:

 Omission of parentheses around method arguments for method calls in
 the argument list may make programs hard to read / parse.

for example,

  p sprintf "the answer=%d\n",42

warns like "warning: parenthesize argument(s) for future version", and
recommended code should be

  p sprintf("the answer=%d\n",42)
