/**
57
-
* The construct below allows to properly distinguish open unions. Consider
58
-
* the following example:
59
-
*
60
-
* ```ts
61
-
* type Foo = { $type?: $Type<'foo', 'main'>; foo: string }
62
-
* type Bar = { $type?: $Type<'bar', 'main'>; bar: string }
63
-
* type OpenFooBarUnion = $Typed<Foo> | $Typed<Bar> | { $type: string }
64
-
* ```
65
-
*
66
-
* In the context of lexicons, when there is a open union as shown above, the
67
-
* if `$type` if either `foo` or `bar`, then the object IS of type `Foo` or
68
-
* `Bar`.
69
-
*
70
-
* ```ts
71
-
* declare const obj1: OpenFooBarUnion
72
-
* if (is$typed(obj1, 'foo', 'main')) {
73
-
* obj1.$type // $Type<'foo', 'main'>
74
-
* obj1.foo // string
75
-
* }
76
-
* ```
77
-
*
78
-
* Similarly, if an object is of type `unknown`, then the `is$typed` function
79
-
* should only return assurance about the `$type` property, which is what it
80
-
* actually checks:
81
-
*
82
-
* ```ts
83
-
* declare const obj2: unknown
84
-
* if (is$typed(obj2, 'foo', 'main')) {
85
-
* obj2.$type // $Type<'foo', 'main'>
86
-
* // @ts-expect-error
87
-
* obj2.foo
88
-
* }
89
-
* ```
90
-
*
91
-
* The construct bellow is what makes these two scenarios possible.
