Thanks! I worried about what might happen in the case of bad or rogue code. Are you referring to OS X's sandboxing capabilities, or something LLVM supports? I agree blindly executing code is possibly a bad idea, although the intent is that someone creates a DSL, and so the DSL's code generator would constrain what could really be done. That is, the DSL would not allow the user to arbitrarily execute hosting code, but rather the DSL's runtime could call hosting code. Does that make sense?
