It has -everything- to do with it when we're talking about the
defining of functions, and certainly a lot more relevance than straw
man arguments on the behaviour of browser buttons.
You said that you "would expect it to define them at execute-time". So
is that when the interpreter first hits the def or when the
interpreter hits every single function call? Because I personally
consider it to clearly occur at the point of definition and not at the
point of calling.
