Is it un-Phobos-like to make append return a reference to data 
like at

I don't now, returning it at least allows chaining, which is nice.

You shouldn't use my code verbatim though. For example, you 
should only use x.length, if x is of element type of data. 
Otherwise if you have e.g. an array of array you'd get totally 
wrong numbers.
