FWIW {stringi} has %+% for this functionality (and I occasionally use
it), tho I do enough processing of quite ughly string content that I
pretty much always have {stringi} loaded. That may not be true for
many other folks.

But sixteen years is a long time in software development and R now stands as something of an exception on this score. Python, Julia, Stata, and SQL (among various others) all support native string concatenation/interpolation using binary/arithmetic operators. It's been a surprising source of frustration for students in some of the classes I teach, particularly those coming from another language.
