Lewis,

Since you are unlikely to draw real blood from that particular stone,
try the folowing function, if you have to do it your way:

function fetch(object a, sequence b)
    integer i,len
    i = 1
    len = length(b)
    while i <= len do
        a = a[b[i]]
        i += 1
    end while
    return a
end function

Or, if you prefer a recursive variant:

function rfetch(object a, sequence b)
    integer len
    len = length(b)
    if len>1 then
     return rfetch(a[b[1]],b[2..length(b)])
    else
     return a[b[1]]
     end if
end function

Btw, I have a strong feeling, the recursive beast can be improved, but
because the first function is always going to be slightly faster
anyway, I do not worry too much about it. jiri
