I've asked this before, and gotten some answers, tried them out, then I 
looked through the code and found some equivalents.

My problem is that I can certain functions over and over again, and 
want to avoid the name to object lookup.

Is this equivalent?

JS_CallFunctionName(cx,obj,"BLECH",argc,&argv,&rval);

To this:

jsval		myfunc;

JS_GetProperty(cx,obj,"BLECH",&myfunc);
JS_CallFunctionValue(cx,obj,"BLECH",argc,&argv,&rval);

Is there any problem with this across garbage collections?  I'd be 
caching the myfunc and using it continually.

It would be nice to have an additional API that got you a JSFunction 
from a name, like:

JS_GetFunctionObject(cx,obj,"BLECH",&fun);

Then I could call JS_CallFunction and the code would make a bit more 
readable, but if this is OK, then this way is good for me.
