In Maxima:

(%i1) sqrt(-1);
(%o1)                                 %i

Thus, there is no problem if you use the variable "i". But, you can assign a 
new value to "%i":

(%i2) %i:2;

(%o2)                                  2
(%i3) %i^2;

(%o3)                                  4

Maybe this is not the best solution, but you just must remember to not use % 
variables.

Probably because the Matlab compatibility thing this approach cannot be 
adopted.
