Re: Chainable template mixin and opCat()

[w0rp via Digitalmars-d]

I think my only complaint for this is that it wouldn't work for 
all ranges, so you'd be able to use the operator some times, but 
not others. This is because you have to define the operators 
inside of the structs or classes, and you can't write operators 
as free functions. (Which is a good feature in general.)
