-------------------------------------------------------------------
TBH, not a big fan of either solution, each is nasty in its own right. I agree
with Robert, using Java Assist means you will always be in a state of catch up
language wise. But relying on eclipse means dragging an elephant of
configuration test matrix problems around with you forever.
My experience with user-provided source code level integration is just a
painful painful thing. I'm not sure it's worth it.
I'm also not a big fan of building prototype java code up in StringBuilders.
Can we externalize the prototype into a first class file that get's
getResourceAsStream'ed in and modified thru markers of some sort?

> Using JDK's built-in Java-Compiler API has some advantages over javassist.
> Although compilation feels a bit slower, Java compiler API has some
> advantages:
> * boxing + unboxing works
> * generics work
> * compiler error messages are better (or at least known) and have line/column
> numbers
> The implementation does not use any temp files. Everything's in memory.
> Patch attached to this issue.
