Neither, actually. It didn't occur to me that there might be an ambiguity any more than it occurs to me that f(3, 4) could be ambiguous in C because the comma might be an operator. I imagined the following rule: If a statement begins with "def", then every | outside parentheses delimits a decorator. If you insist on using an expression with | in it as a decorator, you have to parenthesize it. I can see now that even though this suggestion isn't really syntactically fuzzy, it might be considered too fussy. Still, I like it better than the prefix @ idea. I even realize why I don't like the @ syntax. It's not so much reserving @ as it is that it's a prefix syntax. It is ingrained in me that "def" starts a function definition, and now it doesn't any more. So, for example, if I use my editor to search for "def", I have to back up to see whether I've missed something before it.
