Actually it is covered by the spec.
See:

It clearly says:
```
Each AssignExpression in the ArgumentList is evaluated at
compile time
```
Which means that Br cannot be used in Ar since it cannot be
evaluated at compile time during the mixin of Ar.
That's not what that sentence means. Here's the full version,
without the part you cut off:
Each AssignExpression in the ArgumentList is evaluated at
compile time, and the result must be representable as a string.
The resulting strings are concatenated to form a string. The
text contents of the string must be compilable as a valid
Expression, and is compiled as such.
In other words: the string being mixed in is what's evaluated at
compile-time. The code *inside* the string is treated the same
way as any other code.
