Hmm, see, haven't really thought of lack of exposure as a problem -
maybe because that is because I am already exposed. ^,^

That is vastly annoying. Few other "popular" languages have decent
embedding documentation, however. I think documentation in genreal
needs to be improved for all embeddable scripting languages.

Which is the point. Unfortunately, people hate change. Seriously.
Yes, the bright people like it, encourage it, cause it, etc. Far too
many people, however, refuse to use something "new." This can affect
the popularity of a language. People get upset with Python because of
the block syntax - I don't see a problem with it, it's a good idea for
encouraging students to indent code, but "old school" programmers
generally hate it. I have trouble sometimes with Ruby, because it
forces you to think in OO, while I (having been brought up on C) just
tend to think procedurally. I can code in a C syntax much faster than
other languages, simply because of familiarity.
Of course, you can keep a C syntax while extending it, as well. You
suggestion for variable declarations has actually been used in a number
of game scripting languages I recall from years ago, even tho the
majority of the language kept a C syntax.
Again, this isn't an argument against Lua, whose syntax is nice - just a
problem I keep seeing from people. They don't want change. Lots of
times, even if the developers like the "different" syntax, if they are
publishing a product to be used by customers, they might go with
something else to please them.
