I understand the why for embedded DSLs for things such as database queries, regex and the like but a general purpose embeddable language? I wonder how many users these sort of languages have, aside from its creators and perhaps the company where it has been born. There are tons of embedded languages, many with libraries and all sort of utilities, why should someone invest themselves in such languages with all the risk it takes? Problems such as: additional build steps, security, ecosystem, train employees and maintainers into new languages, additional maintenance barrier, etc
