[Proto-Scripty] Re: how to load scripts dinamically
Excellent, thanks Rob. That's how I *thought* it worked, but I wanted
to check the spec to be sure. Thanks for the reference!

The ECMAScript Spec, section 14 Program says:
| The production Program : SourceElements is evaluated as follows:
| 1. Process SourceElements for function declarations.
| 2. Evaluate SourceElements.
| 3. Return Result(2).
In other words, all the script is read, then execution begins. You
may have issues if the function is defined in a script that is loaded
after a script that calls it.

I don't *think* so, I'll have a look at the spec out of curiosity. In
the meantime, though, there's no reason we can't put the call at the
end instead of at the beginning -- it's not going to cause any
harm... I've updated the page.
Thanks,
