- now, if I put two complex on the stack, say (1,2) and (3,4) and I

more but 2 ->ARRY still works.

This is because ->ARRY and ->V2 don't have the same purpose.

->ARRY is used to build an array of any size.

->V2 is used when you want to build a two-dimensional vector, this
vector having a few representations. According to flag -19, a 2D vector
can be either a complex number or a { 2 } array (with ->ARRY notations).
According to the chosen "coord. system" (rectangular, polar or
spherical), the vector can be expressed and displayed in different ways.

To put it in a nutshell, just use ->V2 when you want to deal with
2D vectors, converting them easily from rectangular to polar coord.
system, or from polar to rectangular coord. system.
