/*
* By popular demand, we define a struct to represent an expression.
* This will no doubt mutate as expressions become baroque.
*
* Currently, we support expressions like "foo OP bar + 42". In other
* words we permit a (possibly undefined) symbol, a (possibly
* undefined) symbol and the operation used to combine the symbols,
* and an (absolute) augend. RMS says this is so we can have 1-pass
* assembly for any compiler emissions, and a 'case' statement might
* emit 'undefined1 - undefined2'.
*
* The type of an expression used to be stored as a segment. That got
* confusing because it overloaded the concept of a segment. I added
* an operator field, instead.
