> Three, the language is not a mere combination of syntax and semantics. Any evaluation should also account for user bases and ecosystem, and in my very humble opinion Lua spectacularly fails at both. I'm not going to assume the alternative reality---Lua has a sizable user base and its ecosystem is worse even for that user base.
> [...] The lack of quality library also means that you are even more risky when you are writing a small program (because you have less incentive to write it yourself). I have experienced multiple times that even the existing libraries (including the standard ones) had crucial flaws and no one seems to be bothered to fix that. Also in the embedded setting the use of snippets, rather than proper libraries, are more common as libraries can be harder to integrate, and unfortunately we are left with PHP-esque lua-users.org for Lua...
I think this critique still holds today, and unless miracle happens (like D), I doubt this is fixable.
Precisely, one of the things that turns me off on Python (coming from Lua), is the unnatural proliferation of different container types.
