Git spare-checkout with nested submodules

	We got a root project (project-a) which has a submodule (project-b). That submodule in turn has a submodule (project-c).
	Each project also contains some files.

	project-a @ 5r210h6/
	├─ some-file.a
	├─ other-file.a
	├─ third-file.a
	├─ project-b @ 196a095/
	│ ├─ some-file.b
	\| ├─ more-file.b

A handy collection of examples of how to work with typescript types

	type SimpleExample = 1 \| 2 \| 'a';
	type ConditionalExample<T> = T extends number ? T : never;
	type T = ConditionalExample<SimpleExample> // '1' \| '2'

	/////////////////////////////////////////////////////////////////////////////
	// Filter out keys from TRecord which's value matches type of TMatch
	type MatchingKeys<
	TRecord,
	TMatch,
	K extends keyof TRecord = keyof TRecord
