I don't like @a.=shift. It looks like @a = @a.shift, which is of course
not what you mean.
In addition, the current @a.shift is useful because it returns the
element that was removed from the array, so you can do something with it:
@customers.push @c if (@c = new_customers());
I'm sure the more experienced people can suggest a better example.
