That implies that it is impossible to implement Scheme:
- using a programming language where variables and objects may move during their
lifetime;
- or using a computing device without conventional memory, e.g. implementing
Scheme using hydraulics, DNA computing, clockwork, or emulated in the human
brain.
I think that's pretty crap. It might be justifiable to define a language like C
to a specific hardware implementation, but higher-level languages like Scheme
should be more abstract.
