The exit keyword edit
exit finishes the execution of the program after valuating EXPRESSION. It returns with this value.
Although exists can be called on arrays also, its behaviour strongly depends to the use of delete on arrays, having a much less clear behaviour.
Syntax edit
exit EXPRESSION
exit
Examples edit
print "Exists\n" if exists $hash{$key};
print "Defined\n" if defined $hash{$key};
print "True\n" if $hash{$key};
