clobbered

Carp Carp takes care not to clobber the status variables $! and $^E in the course of assembling its error messages. This means that a $SIG{__DIE__} or $SIG{__WARN__} handler can capture the error information held in those variables, if it is required to augment the error message, and if the code calling Carp left useful values there. Of course, Carp can't guarantee the latter.

$@

Interpolate. $@ is set if the string to be eval-ed did not compile (this may happen if open or close were imported with bad prototypes), or if Perl code executed during evaluation die()d. In these cases the value of $@ is the compile error, or the argument to die (which will interpolate $! and $? ). (See also Fatal, though.)
