Of course it's idiotic. If you stop to think about it for five seconds, you'd realize that. Compare: Logo versus Ada. Forth versus ML. Lisp versus Perl. Most DSLs with any general-purpose language.
If you think any programming languages are simple, then you have never done any work with them or compilers.
I wasn't referring to the myriad analyses and code generation, but if you really want to, please tell me implementing Forth is the same order of difficulty as Perl.
Not that implementation should have much to do with the language itself (remember that?). Ease of learning a language is largely orthogonal to implementing that language. See: malbolge, befunge, unlambda.
