<lang perl># throw an exception
Perl 5 does not actually support exceptions at all, but they can be simulated with:
die "Danger, danger, Will Robinson!";▼
 
# throwcatch an exception and show it
eval {▼
▲ die "Danger, danger, Will Robinson!";
die "this could go wrong mightily";▼
};▼
# catch an exception and show it
print $@ if $@;▼
▲ eval {
 
▲ die "this could go wrong mightily";
# rethrow▼
▲ };
die $@;</lang>▼
▲ print $@ if $@;
▲ # rethrow
▲ die $@;
See http://perldoc.perl.org/perlvar.html#%24EVAL_ERROR for the meaning of the special variable <tt>$@</tt>. See http://search.cpan.org/dist/Error for an advanced, object based -exception handling.
