Slash is a new programming language that promises to marry the simplicity of PHP (embed a bunch of code in a file and call it directly), but with the elegance of Ruby or Python.
Regardless of that, I found this code snippet from their compiler interesting:
-if git ls-files | grep -v Makefile$ | xargs grep -n '\t'; then - echo "There are hard tab characters in the following source files:" - echo - git ls-files | grep -v Makefile$ | xargs grep -n '\t' - echo - echo "Failing build." - exit 1 -fi
