Good point.  I'd like to point out that the overhead completely depends 
on the number where #to_a is invoked on.  For small numbers the overhead 
is likely significant.  But for large numbers, especially BigNums I'd 
say the overhead is negligible.  But I guess, in reality this would be 
more often used with rather smallish numbers.  So yes, this should be 
taken into account.

Kind regards
