Detailed Description

template<bool B, class returnT>
struct madness::lazy_enable_if_c< B, returnT >

lazy_enable_if_c from Boost for conditionally instantiating templates based on type

Evaluates to returnT if B 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 T is only valid when B is true. Note: typename T::type is the return type and must be well formed.
