+Explanation: Every union literal begins by selecting one alternative and
+specifying the value for that alternative, like this:
+
+
+        Select the ❰Left❱ alternative, whose value is ❰True❱
+        ⇩
+    ┌──────────────────────────────────┐
+    │ < Left = True, Right : Natural > │  A union literal with two alternatives
+    └──────────────────────────────────┘
+
+
+However, this value must be a term and not a type.  For example, the following
+values are $_NOT valid:
+
+
+    ┌──────────────────────────────────┐
+    │ < Left = Text, Right : Natural > │  Invalid union literal
+    └──────────────────────────────────┘
+               ⇧
+               This is a type and not a term
+
+
+    ┌───────────────────────────────┐
+    │ < Left = Type, Right : Type > │  Invalid union type
+    └───────────────────────────────┘
+               ⇧
+               This is a kind and not a term
+
+
+You provided a union literal with an alternative named:
+
+↳ $txt0
+
+... whose value is:
+
+↳ $txt1
+
+... which is not a term
+
+Some common reasons why you might get this error:
+
+● You accidentally typed ❰=❱ instead of ❰:❱ for a union literal with one
+  alternative:
+
+    ┌────────────────────┐
+    │ < Example = Text > │
+    └────────────────────┘
+                ⇧
+                This could be ❰:❱ instead
