+E0248: r##"
+This error indicates an attempt to use a value where a type is expected. For
+example:
+
+```
+enum Foo {
+    Bar(u32)
+}
+
+fn do_something(x: Foo::Bar) { }
+```
+
+In this example, we're attempting to take a type of `Foo::Bar` in the
+do_something function. This is not legal: `Foo::Bar` is a value of type `Foo`,
+not a distinct static type. Likewise, it's not legal to attempt to
+`impl Foo::Bar`: instead, you must `impl Foo` and then pattern match to specify
+behaviour for specific enum variants.

 This error indicates a constant expression for the array length was found, but
 it was not an integer (signed or unsigned) expression.
