Hello there! 👋
While adding
ruby2_keywords
to @DataDog'sddtrace
gem I discovered that it had a few incompatibilities with older rubies.I went through every one of them, and replaced them with alternatives that work as far back as Ruby 2.0.
Out of curiosity, I tested 1.9 as well, and found there were further incompatibilities but I decided to stop at that point 🤣 .
Hopefully this is acceptable :)
