It also has:

dostring (string [, chunkname])
Executes a given string as a Lua chunk. If there is any error executing the
string,
then dostring returns nil. Otherwise, it returns the values returned by the
chunk,
or a non-nil value if the chunk returns no values. The optional parameter 
chunkname is the ``name of the chunk'', used in error messages and debug 
information.
