And what other subtle differences are there between built-in tokens like map and user defined subroutines with a (&@) prototype?

We recently had a similar discussion about the restrictions of prototypes in simulating the behavior of syntax commands and about incomplete documentation.

e.g. here

Re^2: coderefs and (&) prototypes

Hope it helps...

Cheers Rolf
