Add an error message when {#function:inline} macros are used.

Every time I go to call a function and embed the output in a section, I forget whether or not I'm supposed to declare the macro with :inline or not. A specific error message would be nice, because currently what happens if you do the wrong thing (:inline), is you get targetFunction is undefined, which is confusing when you know you've defined the function.

That error message is obviously nonsense, so I'll look into that. But the broader issue here seems to be that :inline is an unclear name... I wonder if that tag should be called something different?

[NQNStudios]

Yeah, to be honest I thought I had it straight in my head and I still don't. The keyword makes the concept fuzzier in my head which makes it hard to think of a better keyword.

[NQNStudios]

To be clear, inline only applies to macros in link destinations and means the link itself transforms, right? Even now I'm not confident off the top of my head.

[invicticide]

Yeah, :inline is what you add to a link destination to say "replace the link with the expanded destination content when clicked". It has no meaning in any non-link context.

Maybe it should just be :replace
