3. Benefits The most significant is productivity increase!
* Productivity proportional to earlier practice

4. Limitations and obstacles
Wrong techniques applied
DSLs are made too broad
Build DSLs based on a solution domain (code)
Manually editing generated code
Some tools are immature. No support for
