Just to make this extra fun.... You CAN change variables after they've been assigned.
If you assign a new value to the variable in a template, it will pick up the new value. Note that this should NOT be used as a feature but I'm sure it'll bite someone like it did me at some point since it lovely and random but, once set, is set for that variable as long as it's memory resident. Note: I haven't checked that this still happens in a while but I would bet that it does.
