They're effectively the identity commands, i.e. `get` returns the value that was passed into it, and -`expand` expands a macro as if it didn't exist. These are useful because, again, -*literally* everythin is a command, so if you want to return a value you can't -just write `arg` as the last element of a `(begin ...)` or whatever, because -that value will be interpreted as a command. Same thing with macros. +`expand` expands a macro as if `expand` weren't there.

Same thing with macros. Note that `values` is effectively the same thing as `get`, but I think `get` has a nicer symmetry with `let`/`set`. `macroexpand` is (maybe somewhat surprisingly) not equivalent to `expand`, as `macroexpand` can't handle |
