I hope my explanation is not rambling nonsense.
Cheers.
Yes, you're right. Passing structure pointers to functions is an
extremely common practice in C, because there aren't really any
other compelling options. In D we have things like methods,
classes, 'const ref' params, return-type inference, etc., so
there's usually a better way to achieve the same result.
