Essentially your argument is one of context and the OP implies through the usr of R that we are talking about real numbers, where $0^0$ is undefined. In other contexts different definitions or conventions do apply. The example of $\displaystyle e^x=\sum_{n=0}\frac{x^n}{n!}$ is a rather amusing one. It's an expression packed with conventions and notational obfuscation.
