GopherLua is a Lua5.1 VM and compiler written in Go. GopherLua has a same goal

GopherLua is a Lua5.1(+ `goto` statement in Lua5.2) VM and compiler written in Go. GopherLua has a same goal

with Lua: **Be a scripting language with extensible semantics** . It provides

Go APIs that allow you to easily embed a scripting language to your Go host

programs.

- ``file:setvbuf`` does not support a line buffering.

- Daylight saving time is not supported.

- GopherLua has a function to set an environment variable : ``os.setenv(name, value)``

- GopherLua support ``goto`` and ``::label::`` statement in Lua5.2.

    - `goto` is a keyword and not a valid variable name.
