Thanks for the pointer, I now have

[Lua]$ cat example.lua
#!/usr/local/bin/lua

function mycall( f )
       local _g = getfenv(1)
       f()
       setfenv(1, _g)
end

s1 = "x = 42"
s2 = "print(x)"

c1 = loadstring(s1)
c2 = loadstring(s2)

mycall( c2 )
mycall( c1 )
mycall( c2 )
[Lua]$

Which seems to work, at least for the example.
