There are two types of code data types in \mbox{\hyperlink{namespace_qore}{Qore}} (see also \mbox{\hyperlink{basic_data_types}{Basic Data Types}} and \mbox{\hyperlink{container_data_types}{Container Data Types}})\+:
\begin{DoxyItemize}
\item \mbox{\hyperlink{code_data_types_closure_type}{Closure Type}}
\item \mbox{\hyperlink{code_data_types_callref_type}{Call Reference Type}}
