I use BEGIN blocks in another way. I do a lot of matrix crunching, so I
look at the input data, determine how big the matrix should be, then
start a BEGIN block and allocate the matrix.

I've never used BEGIN blocks to avoid naming conflicts, mostly because I
can't understand my own code if I use the same name for different
variables in different places!
