The reference to "POD" here is a bit confusing.  By the generally
accepted meaning of the term, structs and unions would in fact be POD
just like any other C type.  But you seem to be using the term here to
mean something along the lines of "non-aggregate type", which isn't a
usage I've previously encountered.

This is particularly confusing in this context because there is a
different clang limitation which applies to VLAs where the
variable-length element is not POD, irrespective of whether it is inside
an aggregate or not, and someone reading your comment might be misled
into thinking that this was the issue here.
