# booleans are lambdas or values?
    # well, if they're lambdas, then they're read by the init file?
        # if they're user-defined, then what should comparisions return?
            # maybe they just return what 'true' or 'false' would return in the \
              given envronment?
        # also keep in mind that if they're values, we'll need a builtin \
          conditional switch function in addition to them.
        # it's probably best if they're builtin lambdas, like '+' or '×'.
