wow... i thought the "a" variable is kind of like in C or Python:


for (i = 1; i <= 2; i++) {
int a;

if (i==2) {
...
} else {
...
}

}

so that the "a" exists all inside the for loop... maybe that's not
right.

now, we can view the variable "a" as existing in the else block but no
where else in the original Ruby code?
