it might be interesting to compare the speed of  t[#t+1]=exp versus 
table.insert (t, exp), since it's in the inner loop a small difference could 
be significant.

i guess it should be the same, unless the insert() function uses a different 
way to determine the 'end' of the array.... it was a hot topic in the design 
of 5.1, i don't remember what was the final decision.
