Ironically, many of the places I see implicit concatenation used are
where people need to work around linters complaining about line
lengths. I understand the benefits of projects that mandate code
passing lint checks, but I foresee sequences of commits:

"Modify error X to be clearer"
"Linter fix - split new message onto 2 lines to avoid long line"
"Linter fix - explicitly concatenate with + because implicit
concatenation is discouraged"
"Linter fix - go back to the old message because the stupid linter
complains about unnecessary addition of 2 constant values and I can't
be bothered any more"

Ok, the last one is a joke - but getting a set of rules that doesn't
back the programmer into a corner where it's non-obvious how to
achieve a simple goal could easily become a non-trivial task.
