Nice idea, but it seems it only works on the command line where we have 
proper quoting, not as a shebang:

    #!/usr/bin/env LUA_INIT='assert(_VERSION>="Lua 5.2")' lua
    print( "hello from", _VERSION )

hangs when called as `./test.lua`. Calling it via `lua test.lua` just 
skips the shebang obviously ...
