I wrote 5 compilers in college in 4 different languages / language paradigms. Then after college I wrote an interpreter that would call c++ code. The interpreted language had C++ like syntax with exceptions, etc. Performance was terrible, but it worked.
That was all 14 years ago, so I am a tad rusty.
Last time I wrote a compiler was about 20 years ago. Most of my stuff was really simple though. I wrote a lot more interpreters than I did compilers.
