A-ha - I think you're right. For example I tried this:
lg_ldr = new Loader();
try {
trace(lg_ldr["unloadAndStop"])
} catch(e:Error) {
trace("error")
}
With FP9 as the runtime, catch handles it. With FP10 as the runtime,
'function...' is traced.
Now I just need to find something a little less weighty than Loader to test
against. :)
