use MyPackage qw/arg1 arg2/ ;

If this is supposed to export subroutines arg1 and args2, you can use the Exporter standard module:

package MyPackage;
require Exporter;
our @ISA = qw(Exporter);
our @EXPORT_OK = qw(arg1 arg2);  # symbols to export on request

Of course, if you want to do something else with those args, you can get creative with your custom import subroutine as shown by Golo and trammell above.
