Yes, it is more expensive. On my machine (W2K 750MHz PIII) this code:

    for i=1,100000 do
        local f = getglobal("Test_Version")
        f()
    end

Executed in 0.12 seconds, while this code:


    for i=1,100000 do
        dostring("return Test_Version()")
    end

Executed in 1.262 seconds.

So about a factor of 10 slower. 

However, I have to say that 12.62 microseconds to execute the
"dostring" version is pretty darn fast, plenty fast enough for many
situations.
