📝CPS is not the same as SSA
CPS is not the same as SSA. There are similarities between them but focusing only on the fact that all variables are bound once in CPS dismisses other differences.
In reality, the two forms are very different to work with, so focusing on that one similarity is not helpful and is misleading. It’s like saying that any two languages are the same because they are turing-complete and can technically be converted to one another.
