It should be possible to teach Axiom to distribute limits through sums and products as in

fricas
limit(product((1-q^(N-i))/(1-q^(m-i)),i=0..m-1),q=1)

\label{eq1}\prod_{
\displaystyle
{i = 0}}^{
\displaystyle
{m - 1}}{{- i + N}\over{m - i}}(1)
Type: Union(OrderedCompletion?(Expression(Integer)),...)

However, it is not clear to me where this should be done. Limits of this kind are currently handled in limitps.spad, where Axiom tries to do a Puiseux expansion of the expression.
