Advantage of your proposal:

- easy to extend the language without breaking existing code.

Disadvantages of your proposal:

- The advantage is also a disadvantage: a lowered barrier for
   new semantics could bloat the language definition. Python's
   strength is that it has *few* concepts that are usable in *many*
   places. This could be compromised by your proposal.

- Python is a readable language. lambda says "function literal",
   yield says "generator", @ just says "different". Python would
   be less readable if this notation would be adopted.

Therefore I vote against it.

Mit freundlichen Gruessen,
