No problem -- it's interesting to see which bits I've forgotten to
document enough, and I'm sure others are finding it illuminating too ;)

Yes, someone else asked about the get_metadata() method.  I think,
fundamentally, I need to fix it so it will work properly; in some
circumstances it will not return metadata unless the content item has
been read :(

BTW you could also subst the string '$['.$pg2->{name}.'.up]' -- the
two are equivalent.

no, it is not; firstly, you will probably get a warning along those lines,
but it's a red herring.  (The development version at the moment includes a
fix for that anyway.)

the real problem is the get_metadata() method not working in an intuitive
way.  To make sense (!!) it should operate exactly the same as the
quiet_curly_meta_subst() above.
