I think that just because of the way the parser works, certain implementations
and syntax structures are allowed - and able to be properly recognized/tokenized
and accepted by the parser, and others aren't.

You may have to resort to reading in your csv file with a loop and individually
assigning array elements.

try getting rid of the [16] and see what that gets you.
try your nice little () parsing trick
maybe a macro inside the {} would work

I got tied up with a surprise project, and it's eating up my weekend.
