Agreed. At the time it was just a really quick idea I had for Ruby-like string interpolation. What would you replace eval($1) with to make it more secure? I guess you could start by processing the expression for assignments or function calls so the expression can only contain an R value (without method calls).
Ah, forget I asked. Just noticed your fork. Thanks for the work!

you should replace
eval($1)with something smarter because it opens a big security hole.
