Fixes #44896
Fixes #50455

I actually don’t think this is a breaking change in any meaningful way. I do have one test that exhibits new errors, but the scenario is extremely contrived and didn’t exactly work before. Mostly, this removes false errors and false import elisions. The most visible and understandable example is the one from #44896:

// @filename: constants.ts
export const COFFEE = 0;
export const TEA = 1;


// @filename: drink.ts
export type Drink = 0 | 1;
export * as Drink from "./constants";


// @filename: index.ts
import { Drink } from "./drink";
// 👀 BEFORE: 'Drink' only refers to a type, but is being used as a value here
// 👍 AFTER: No error
const x: Drink = Drink.TEA;

Heya @andrewbranch, I've started to run the parallelized Definitely Typed test suite on this PR at a97a11e. You can monitor the build here.

Why is this not an error? Since we're exporting as type-only something that is not a type.

to check my own understanding, this is an error because we don't allow the function value to merge with the namespace?

That’s right, but only because A is an alias. Normally, slightly disconcerting though it is, we allow a function to merge with an instantiated namespace: playground. I only learned this in the course of my PR, but the rules are stricter for merges across module boundaries (thankfully). Two values are just not allowed to merge across modules.

I think that's covered in the tests, but what's the consequence of changing this check's order?

It’s been a while, but I believe it’s this:

A namespace is a value if it exports values. If it’s not a value, it’s not a type per se, but it’s fairly typey. I believe after tweaking the meaning flag checks in these functions to be a bit easier to read, the checkAndReportErrorForUsingTypeAsValue started reporting an error on typey (uninstantiated) namespaces, which was stepping on the toes of checkAndReportErrorForUsingNamespaceModuleAsValue, which wanted to issue essentially the same error, but slightly more precise in mentioning that the non-valuey thing is a namespace. So I simply moved that check first so it would take precedence. So I actually think this order change isn’t reflected in the tests, because it just neutralizes the effect of another readability change. (I also renamed checkAndReportErrorForUsingNamespaceModuleAsValue to checkAndReportErrorForUsingNamespaceAsTypeOrValue because nobody knows what a “namespace module” is, and it was already issuing errors when using a namespace as a type.)

LGTM, though I'm not sure I'm a massive fan of the ?? -1; it seems like most call sites do that but I don't know if I have any better method, besides maybe SymbolFlags.All or something, but that still requires the ??.

I might look at making getAllSymbolFlags opinionated and say that unresolved aliases return SymbolFlags.All, and make a variant that returns undefined for the few places that need to do something different. I think it’s probable that a lot of the places that currently see SymbolFlags.Property would have the same behavior seeing SymbolFlags.All.
