Detailed Description

template<class CALLABLE>
struct bslstl::CallableVariable< CALLABLE >

This metafunction returns a type that is an alias for CALLABLE unless that is a function type, in which case it is an alias for CALLABLE &. This should be used to declare variables of an arbitrary callable type, typically a template type parameter, that may turn out to be a function type. Note that this metafunction is necessary as the C++ language does not allow variables of function type, nor may functions return a function type.
