Meta note — would you mind editing your post to add a little more context? Some of us are on slow / metered internet, so opening a random PDF is a bit of a risk.

Seems like I'm not the only one with unreliable internet. Thanks for the edit!

Abstract. Given all the different benefits that domain specific languages are reported to produce, why are they not a widely adopted practice? In this report, we try to condense [... some possible reasons voiced and possibly related concerns expressed ...] in a short coherent text.

11/26/2020, 2:42 AMI'm surprised they don't talk about lack of composability: the simple fact that coming up with a good DSL is trickier than coming up with a good API, which is tricky enough.

11/26/2020, 2:49 AMthat's a fair point, composability is hard to achieve. I think of SQL though, it is extremely popular DSL even though it is not highly composable. I remember one of the "killer features" of ActiveRecord on rails was the "relational algebra library", which allowed to pick an existing query and add one more constraint in a single line of code, which is not easy with plain-text SQL

11/26/2020, 2:54 AMI'm thinking for something like Tax rules having some redundancy because of lack of composability maybe is not a great deal, perhaps it is even a feature. Instead of saying "Tax rule #77 is like Tax rule #23 but with XYZ", you may need to copy and modify the old rule ... there would be no risk one rule changing modifying the other.

in any case for me the takeaway is that lack of composability can be alleviated with great tooling if the DSL provides enough advantages.
