That shouldn't be necessary.

[conv]: Certain language constructs require that an expression be 
converted to a Boolean value. An expression e appearing in such a 
context is said to be contextually converted to bool and is well-formed 
if and only if the declaration bool t(e); is well-formed, for some 
invented temporary variable t (8.5).

I'll take a look at this bug.
