Unfortunately, that's not really true: the Pascal strings it supports
are in some sense variable length, but are stored in a fixed-width
field. The internals of the struct module rely on each field starting
at a fixed offset, computable directly from the format string. I don't
think variable-length fields would be a good fit for the current
design of the struct module.

For the OPs use-case, I'd suggest a library that sits on top of the
struct module, rather than an expansion to the struct module itself.
