Thanks for the explanations and advice. APL isn't as fast as I'd like, so I thought LLVM would be nice, but then you lose REPL functionality I believe which is vital for this kind of language. Julia JITs every expression to LLVM (I think)which is how it has a REPL, so that seems like a good choice to get said REPL. So maybe just the Julia route would be smart. It appears to be taking off in the areas that APL, J, Matlab, Numpy, Octave, Mathematica have typically reigned supreme in.

If the compiler is fast enough, then one could make a REPL out of it (by modifying it slightly). LLVM also has interpreters. The trick would be finding a consistent way of representing high level state in the REPL (You can't just lob bits of LLVM IR together), unless you can manage without (of course).
