I've programmed some languages...

So, /prog/, I have programmed some languages, most notably brainfuck and befunge. These languages are fairly simple to implement, but I want to implement something a bit more challenging. I'm probably not EXPERT PROGRAMMER enough to program some fully featured advanced language just yet. What is the next best language to program?

Thanks,

Arnold

It's all about you, isn't it? ``Me me me me me me.'' Well, I'm afraid you don't have any choice in this matter, you're programming a trefunge-98 compiler and that's the end of it. Thread over.
