As a small data point, I've previously used @ as an extendo character
for various local syntactic extensions that get preprocessed into
plain-Lua source underneath. (I dealt with the source name ambiguity
in another way that I don't immediately recall.) This isn't anything
particularly active or visible right now, but it would be an extra
change if I decided to port to Lua 5.2 and @ were now a label prefix.
I vote for some sort of double-colon marker.
