I guess also run for the hills anytime you find a place using any non-trivial amounts of Ruby, Python, TCL, Perl, Lisp, Scala, or Haskell right (all languages where embedded DSLs are rampant)?

I've worked at places that had great DSLs (both embedded and freestanding) and awful crocks that were just the right mixture of infinite funding and no accountability. The vast majority were trying to make something like database access a little nicer for their domain. Someone who doesn't want to litter their resume with the term "DSL" might even call the majority "libraries". I've certainly seen a couple that were on the level of JDSL ("Why don't we WYSIWYG build a CMS by generating XML which can expand out into PHP"), but I've also seen "writing assembler sucks! there is no C compiler for this micro! it would be way easier to write scheme ... hey look! we have a DSL for writing ECUs". In my anecdotal experience, DSLs have been the only way to stay sane in certain domains.
