this needs more (any) testing but just throwing it up for now, its quite possibly not too good! but i think the results can be pretty desirable.

Maybe because it's just that simple. A test case would be need however.

This logic has since been moved here.

I'm mostly indifferent to this change. But if we are going to change this then we should at least remain consistent:

const <tdef>Foo</tdef> = struct {};
var <>foo = Foo{};
const Foo = <def>struct</def> {};
var foo = <>Foo{};

Either both go to Foo or both go to struct.

This will also need to handle cases like these where it needs to fall back to the old behavior:

const s = (struct { alpha: u32 }){ .alpha = 5 };
const Foo = (struct {});
var foo = Foo{};

try testDefinition(
\\const <tdef>A</tdef> = struct {};
\\const <tdef>B</tdef> = struct {};
\\fn fo<>o(_: A) B {}

this fails, need to update the tests to work with array_of_DefinitionLink
