Dynamically naming arrays

Hey guys, just a quick question.

I’m attaching a bunch of movieclips to the stage, and I’d like each movieclip to have its own array based on the movieclips name. I thought I’d do it the same way that I do it with Movieclips, utilizing the [ and ] brackets like below:

var ["movieclip"+i]:Array = new Array();

I’m getting an error thrown at me, telling me that the line requires an identifier. Is this possible? Or will I have to create the arrays before publishing the file?

Thanks
