http://www.digitalmars.com/d/1.0/statement.html#CaseStatement
"The case expressions must all evaluate to a constant value or array. They must
be implicitly convertible to the type of the switch Expression."

http://www.digitalmars.com/d/2.0/statement.html#CaseStatement
"The case expressions must all evaluate to a constant value or array, or a
runtime initialized const or immutable variable of integral type. They must be
implicitly convertible to the type of the switch Expression."

So the code is illegal.  Clearly this is a mistake in TDPL.

Though I am made to wonder why this restriction is there.  Changing to
enhancement for the meantime.
