What is interesting about this is that we can write procedures which construct other procedures. This is not to be confused with the ability to construct S-expression representations of procedures; that ability is shared by all of the interpreters we have examined.

The ability to construct procedures was not available in the dynamically scoped interpreter. In solving the violation of referential transparency we seem to have stumbled across a source of additional abstractive power.
