Yes, at times I feel like I'm in square peg round hole territory. Usually
when I reach this point I try to take a step back and do things in an
Erlangier way. I now see the reasoning behind why Erlang implements eval
metacircularly. However, if there's one thing that sets scripting languages
apart from other languages I believe it's extensive use of eval and runtime
code generation/execution. In that regard you might call Lisp the world's
first scripting language (although I believe that honor is typically
attributed to awk)
However, it's a lot easier to write a metacircular evaluator for a Lisp than
for something like Reia...

I'm okay with hacks as long as they work :)
