I'm in general not in favour of piling in special symbols into a language

As I went on to demonstrate, function-like syntax (or even actual functions)
could do that job better, by describing what the operation does and not
leaving people scratching their heads so much when they encounter that
funny-looking operator hidden in 20,000 lines of code.
As for '@', if a variable name can come before it /and/ after it, and either
or both can be dotted, wouldn't that cause it to be highlighted as an email
address in many circumstances? Such as in code posted here.
(OK, let's try it and see what happens. My Thunderbird doesn't do previews
so I will have to post it first:
abc@def
a...@def.ghi)
I would find that rather annoying.
You're way WAY too late to debate the matrix multiplication operator.
/The/ matrix multiplication operator?
In which language? And what was wrong with "*"?
(I've implemented matrix multiply in a language (although for
specialised matrix types), and I used the same "*" symbol as was used to
multiply anything else.)
Anyway this is not matrix multiplication, but replication, and using '@'
seems more a consequence of there not being any better ones available as
they are already used for other things.
