On: raising the semantic level of a program

Hi, Not hardware ... but an antique software / programming concept. Some decades ago (circa late 1970s?), I *think* I came across a concept of "raising the semantic level" of a program by using defines/macros and newly written library functions. The concept was that a given language provided a particular level of semantics. By judicious/clever use of things like macros, one could "raise" the level of semantics, effectively appearing to add new features to the language (or, in this case, the instance of the language as used in the program). I *thought* I got that concept from Terry Wingrad's excellent "Breaking the Complexity Barrier again" (Nov, 1974, https://dl.acm.org/doi/10.1145/951761.951764 ) ...but, no. It's not in that paper. Does the concept ring a bell? Can anyone provide a pointer to where I might have seen it? It's formed the basis of my own personal programming philosophy for nearly 50 years, and I want to know where I found it, or if I might have thought of it myself. thanks! Stan
