Well, I found the answer to my own question eventually.

In the interest of anyone also wondering:

No var declaration for globals

Although, I personally don’t agree with it, but thats at least why some Yahoo’s don’t use it.

The original code works in the latest 9.50 beta snapshot, as does the OperaSafe code.

I agree, it seems like you’re trying to use the callback before it may be defined. I think your twitterbadgeOperaSafe code is just fine as is, and doesn’t need to be labeled as OperaSafe at all.

Just a question though, why no var declaration?

Kangax is right, deferring the insert works. This would simulate what is happening in the other browsers. You would only need a millisecond, that’s enough to push it to the next round.

Quick question: If Opera is executing the script right there in mid-function, why isn’t it scoped by that function? This seems really wrong or inconsistent with load time behavior, why isn’t then the second included script on page then evaluated mid execution of first script, when it arrives?

It would be preferable if it were safe to run an include in mid-function. I agree that this isn’t really a bug, as such, but rather really unfortunate behavior. I don’t know about you guys, but I usually “assume” that my lines of code are run in sequence. :-)

What about deferring script insertion?

setTimeout(function(){
document.getElementsByTagName(’head’)⁰.appendChild(s)
}, 10);
