Well JScript uses Reflection AFAIK and for something like GHP, it needs to be 
fast as its counterpart(speed isn't the first concern, but if I can avoid 
this problem now by not using Reflection, I will).  Does Mercury also use 
Reflection?  

I'm thinking about Parrot Assembly for this project instead.  I need to look 
at what pnet has for parrot codegen.  Anything you guys can tell me off the 
top of your heads?
