Lua 1.0 was designed in such a way that its object constructors, being then slightly different from the current light and flexible style, incorporated the data-description syntax of SOL (hence the name Lua: Sol meaning "Sun" in Portuguese, and Lua meaning "Moon"). Lua syntax for control structures was mostly borrowed from Modula (if, while ...
Tarantool uses Lua as the stored procedure language for its NoSQL database management system, and acts as a Lua application server. TeamSpeak has a Lua scripting plugin for modifications. TI-Nspire calculators contain applications written in Lua, since TI added Lua scripting support with a calculator-specific API in OS 3+.
Lua patterns deliberately lack the most complex regular expression constructs (to avoid bloating the Lua code base), where many other computer languages or libraries use a more complete set. Lua patterns are not even a subset of regular expressions, as there are also discrepancies, like Lua using the escape character % instead of \, , and ...
By default, it references a function — first class objects, remember. — that does iteration over a table. # expects the array convention. If your table isn't adhering to that convention, you'll get funny results. Use nil == next (table) to check for a table being empty. When tonumber fails, it returns nil. This isn't C.
The primary function of a foreign function interface is to mate the semantics and calling conventions of one programming language (the host language, or the language which defines the FFI), with the semantics and conventions of another (the guest language).
