One similarity that I don't think has been mentioned yet:
- decorator syntax says, "run me later, after this function is built"
- late-bound argument syntax says, "run me later, just before each function
call"
Because both mean "run me later" we can leverage the @ symbol to aid understanding; also, because "run me later" can
completely change the workings of a function (mutable defaults, anyone?), it deserves more attention than being buried
in the middle of the expression where it is easy to miss (which is why I originally proposed the ? -- it stood out better).
