Contributing

Contributions are very welcome! I will happily accept your pull request if it:

• has tests
• looks reasonable
• does not break backwards compatibility

## Security notes

• Every object/function you pass to sandbox must be contextified. Every object/function you receive from sandbox must be decontextified.
• Every function you call cross-sandbox must be wrapped into try/catch and caught error must be contextified or decontextified.
• Internals must not use any of sandbox's globals (Object, WeakMap, etc). Host's globals must be used instead.
• Reflect must not be used at all since it changes context of arguments passed trough construct and apply methods.
• Almost everything in sandbox can be messed up so use host.Array.prototype.map.apply([], Decontextify.arguments([method])) rather than [].map(method).
