Sure you do (as someone working in modular forms)! Infinity is the point at infinity of the projective line over the complex numbers (which is a 2-sphere). z<-->1/z exchanges complex infinity and the origin. That way you can speak about functions holomorphic at infinity etc... Now we could also equip the complex plane with a "circle at infinity". This is the Stone Cech compactification. I guess this is just not the right thing for complex analysis.
