Being a programmer... ;)

Hmmm. I am split whether he should have brought six or seven bottles of milk.

@nickhh I think 6 because I didn't see a plus or a and clause.

To me it will be like this.

milk = 1;

if (hasEggs){
milk = 6;
}

return milk;

So the second milk variable would overwrite the first since it will be the same variable.

Exactly @fyroc

My interpreter parsed it like this:

buy_milk 1

if hasEggs
buy_milk 6
end
