You can't override Variant[] because '[' and ']' are not allowed in 
project file names.

You can do that by creating the source file by hand, but you may have 
problems - This is the reason why it is forbidden. :-)

I don't see what the real problem is with replacing all occurences of 
Variant[] by something like "MyTokenArray".
