Ordered a copy of the Lua book as the language seemed quite
interesting and potentially useful. The full text was available on the
'net, but I like to read this sort of material whilst travelling.

Although it starts out describing quite a nicely structured language
(occasionally similar in concept to, but never as readable as Python)
as the book proceeds, the more in-depth examples become harder to read
(a lot more like Perl) and having finished the book I was left feeling
that the core language offered nothing useful over Python, in fact it
was rather lacking in many areas.

Don't get me wrong, I know if I had a good enough reason I could quite
quicky and reasonably happily start developing in Lua, but it's
unlikely to ever come close to Python for general purpose coding. That
said, it may well fit the bill for a new embedded low-spec PC-based
device we'll be starting development on in a few months time. The
Python runtime is just too big and this is one area where Lua wins
out, so we'll just have to wait and see.
