Guilty on all charges. Confused the behaviour of static and dynamic
arrays with sizeof.

Ah, thank you!
The problem was I read the way T[].sizeof behaves on static arrays,
thinking I was reading the section on dynamic array properties.

It should work if you treat the dynamic array like a pointer and a length.
eg:
glBufferData(GL_ARRAY_BUFFER, (vertices[0]).sizeof * vertices.length,
vertices.ptr, GL_STATIC_DRAW);
It's probably because (type).sizeof gives the number of bytes to hold the
type.
For dynamic arrays

Are you sure that vertices.sizeof is right? It can be wrong. Maybe you want
something like:
(vertices[
