The problem here is the test condition is not being executed.  In theory, "i +=
some_other_function()" 
could increment i beyond the value desired in the for loop conditional-clause.
The Lretry would not 
officially retry the test condition and could, therefore, potentially execute on
values of i that are 
undesired by being outside the scope of the for loop, introducing a trait that a
well-written program 
should not include.
