\chapter Built-in Exceptions The \Q interpreter supplies its own built-in exceptions, as well as recognizing user-defined exceptions. (See \l throw.) \PRELIMINARY The list of built-in exceptions is listed here: \list \omit \i \Func ImportFailedException -- raised by \l{import}. The import failed because the imported file contains a syntax error. \i \Func ImportNotFoundException -- raised by \l{import}. No matching file could be found to import. \endomit \i \Func ConstAssignException -- raised if an attempt is made to assign to a constant. \endlist
