You can try just to use dpp:
https://code.dlang.org/packages/dpp
instead of doing the translation manually.

Compile as static library some.c, add to command line of dmd.
Should be this simple more or less, depending on compilers and target
involved.

It is arguable whether D's ranges are iterators but if nouns are useful,
we call them ranges. :) (Iterators can be written in D as well and then
it would really be confusing.)

Is it possible to write an iterator that does the following,
using a struct and some functions?
- Operates in a foreach loop
- Has BEGIN-like and END-like blocks or functions that are
executed automatically, before and after the iterations
- Initializes variables in the BEGIN block that are

You'd have to string mixin the contents inside the mixin
template.
Worked!

Want
mixin mytemplate!("foo", .);
to be able to declare names dependent upon the text foo in the
context it is used.
For example declaring
enum x_foo = ;
blah foo_value = ;
