- Enhance gsub so that when it detects repl=="%0" it does not create the
output buffer, so it is as efficient as in your proposal. There is even a
bonus - no need to introduce a new special case for the library users.This seems to me equivalent to my proposal: it would require
documentation (otherwise users won't know it's efficient!) and
possibly slightly more complex implementation than my suggestion.
Also, it's not obvious to someone reading the code that there's
anything different about it.
I was worried about efficiency and expressivity in the case of using "%0"
, so I would say that I'd prefer both of your options to be implemented.
