I notice that that page says "In most settings not involving continuity in the exponent, interpreting 0^0 as 1 simplifies formulas and eliminates the need for special cases in theorems"
Most settings? Are there ANY settings (not involving continuity in the exponent) where interpreting 0^0 as 1 is inappropriate?
