* This header is included only in other .h files, for convenience and for
* simplicity of type naming. The alternative for structures is to use tags,
* which are named the same as their typedef names (legal in C/C++, and less
* noisy than suffixing the typedef name with "Struct" or "Str"). Instead,
* all .h files that include this file may use the same typedef name, whether
* declaring a pointer to struct type, or defining a member of struct type.
*
* A few fundamental scalar types are defined here too. Neither the scalar
* nor the struct typedefs should change much, therefore the nearly-global
* make dependency induced by this file should not prove painful.

* or function call: just before execution begins and just after it finishes.

*
* The 'closure' param is as passed to JS_SetExecuteHook or JS_SetCallHook
* for the 'before'invocation, but is whatever value is returned from that
* invocation for the 'after' invocation. Thus, the hook implementor *could*
* allocate a structure in the 'before' invocation and return a pointer to that
* structure. The pointer would then be handed to the hook for the 'after'
* invocation. Alternately, the 'before' could just return the same value as
* in 'closure' to cause the 'after' invocation to be called with the same
* 'closure' value as the 'before'.
*
* Returning NULL in the 'before' hook will cause the 'after' hook *not* to
* be called.
