When I first started reading the PEP, I was rather dubious about the
choice of @ as operator, but it surprised me at how quickly I got used
to it. I suppose because unconsciously I associated it with the common
shorthand implying (scalar) multiplication:
5kg of apples @ $2 per kg costs $10.00
so it didn't take me very long to warm to it.
