+\description{
+Designed to allow more human readable code that is executed inside a module as well as simple variable substituion
+for injecting constants (e.g. simple parameters or file paths used inside and outside of modules)
+}
+\details{
+This pattern also allows dependency injection which could be used if you don't want to use and renv and (instead)
+would like to use docker images or just execution in the base environment for testing/debugging
