[[gAData]] is still not convertable to a string, so I don't see how that 
could work.

But who cares :-) ?

For some cases - basically simpler ones - the string parsing works 
nicely, though it can be a bit untidy when you are passing variables.

For 98% of the others, an array of named/optional parameters works well 
(and you can use tricks/functions to make that less verbose).

doSomething 12, 4, _("size", tSize, row, gAData)
          works well for me, is probably anathema to some (many?) others

and for the last 2% where you want named, optional, pass-by-reference 
parameters - you're out of luck,  maybe LCB will help some day.
