I think code style like:
db.select(User).where(email.like("*@hotmail.com")).limit(10);
You need to read about templates in D, here's a good guide:
https://github.com/PhilippeSigaud/D-templates-tutorial
Basically you can write a function like
auto select(Class, string fieldName)(Class value) {
...
and call it later as
select!(User, "name")(u);
Here User and "name" are compile-time arguments, you can pass
there types, values and more exotic stuff like other templates.
And inside the function you can use
__traits(getMember, u, fieldName)
to get field by its name from the passed value.
See: https://dlang.org/spec/traits.html
