Consumes the topmost 2 values of the stack, storing the topmost stack value into a variable described by the next value down the stack.
The variable will always be stored at a global scope, overwriting whatever else was there if the variable already existed.
It will ignore local scoping and never store the value in a local variable
It's impossible to make a variable that hasn't been given an initial value. Its the act of storing a value into the variable that causues it to exist. This is deliberate design.
