Detailed Description

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

lazy_disable_if_c from Boost for conditionally instantiating templates based on type

Evaluates to returnT if B is false, 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 B is false. Note: typename T::type is the return type and must be well formed.
