DSLs have been around in the LISP world forever. The tools for building them and for integrating them into the existing toolchain are far more advanced than in the JAVA world. For an example, see

or

The traditional alternative to a DSL is a well-designed domain specific library written in a traditional language. It is useful to consider how such a library avoids disadvantages to DSLs that are not mentioned by Ghosh.

Documenting a new language in sufficient detail that new users can avoid traps and pitfalls is not easy and requires significant effort.

As a DSL inevitably grows, the interaction between language features and with its execution environment becomes poorly understood and buggy.

Tool support (as found in a modern IDE) for a large codebase is mandatory and requires significant effort. "grep" is not sufficient.

Learning a language that is only used in one location is often seen as a "career limiting" non-transferable skill, so it can be difficult to employ good staff.

The ability for non-programmers to write the application in the DSL runs into the well-known problem most simply expressed as "Make it possible for programmers to write in English and you will find that programmers cannot write in English".

Well-designed libraries are more verbose, but avoid those problems
