It should come as no surprise that we like to write those build actions
in Scheme. When we do that, we end up with two @dfn{strata} of Scheme
code@footnote{The term @dfn{stratum} in this context was coined by
-Manuel Serrano et al.@: in the context of their work on Hop.}: the

To describe a derivation and its build actions, one typically needs to
embed build code inside host code. It boils down to manipulating build
