Who uses that, except code generators? I'd like D to deprecate the comma 
so it can be used for other things, like tuple assignment.

Well, it's sad that syntax is not very important in D. If you have to 
write less code there will be less chance for bugs and it will be more 
understandable (unless you obfuscate the code, obviously).

Here's what you can do in Ruby:

a = 1
b = 2

# Swap the contents
a, b = b, a

Can you do something like that with templates in D, with a nice syntax?
