Detailed Description

Compilation data that the embedder can cache and pass back to speed up future compilations.

The data is produced if the CompilerOptions passed to the compilation functions in ScriptCompiler contains produce_data_to_cache = true. The data to cache can then can be retrieved from UnboundScript.
