Safe programming languages o?er safety and security f- tures making them attractive for developing extensible environments on a wide variety of platforms, ranging from large servers all the way down tohand-helddevices. Extensibleenvironmentsfacilitatedynamicho- ingofavarietyofpotentiallyuntrustedcodes. Thisrequiresmechanisms to guarantee isolation among hosted applications and to control their usageofresources.
