On a related note, I just read cstr 99 - Bell's computing research 
history and one of Doug's early articles was mentioned:

M. D. McIlroy, "Macro Instruction Extension of Compiler Languages," 
Communications of the
ACM 3 (April 1960), pp. 214-220.

It's discussing the general extensibility that macros provide and I was 
interested to obtain a copy to read at leisure. I found it over on ACM's 
digital library:

https://dl.acm.org/doi/pdf/10.1145/367177.367223

But, the copy's not that great on my deteriorating eyesight. Does 
anybody have a cleaner copy?

Lately, I've been vastly improving my vi/vim skills and part of that 
process is shifting from an ad-hoc process to a move, act, repeat 
mentality (thank you Drew Neil for that revelation) and macros are 
consonant with this line of thinking :).
