template<class Cond, class returnT>
struct madness::lazy_enable_if< Cond, returnT >
lazy_enable_if from Boost for conditionally instantiating templates based on type
Evaluates to returnT if Cond::value is true, otherwise to an invalid type expression which causes the template expression in which it is used to not be considered for overload resolution. This "lazy" version is used if returnT is only valid when Cond::value is true. Note: typename T::type is the return type and must be well formed.
