The value comparison operators are eq, ne, lt, le, gt, and ge. Value
comparisons are used for comparing single values.
The general comparison operators are =, !=, <, <=, >, and >=. General
comparisons are existentially quantified comparisons that may be applied
to operand sequences of any length.
I don't think that applies here. Or rather, we have different ways to
deal with operand sequences of length greater than 1.
