CAS bug: limit of (1+1/n)^n

[Han]

The extra parentheses are needed to prevent ambiguity between:

\[ \lim_{n\to \infty} (1+1/n)^n = \left( \lim_{n\to \infty} (1+1/n) \right)^n = 1^n = 1 \]

and

\[ \lim_{n\to \infty} (1+1/n)^n = \lim_{n\to \infty} \left( (1+1/n)^n \right) = e \]

Should the limit operator have precedence over exponentiation? or the other way around? To remove any doubt what you intended to compute, use the extra parentheses. (More reason for the devs to get RPN into a better state :-)
