Sets the codes that will be untrapped in the Safe.pm module, used for
embedded Perl and conditional operations. You can see the Safe.pm
documentation by typing perldoc Safe at the command prompt. The default is 249 148 for Perl 5.003, and ftfile sort for Perl 5.003_20 and above, which untraps the file existence test operator
and the sort operator. Define it as blank to not allow any besides the
default restrictive operators.
