Thanks - they tend to visualize long segments of text in a simpler way.

I simply collected what I felt was the opinion of the majority of posts
on the list thus far. Personally, I care little about the exact language
as long as it is relevant and optimal for writing the compiler.

Since Java lacks low-level memory management capabilities, and the 
JVM obviously needs to deal with these issues, I would be somewhat 
hesitant to write the full JVM in Java myself. 

Of course, we could simply contain these services within the OAL, and
fire away.

Good - I will update the text on the site to reflect that.

I am uncertain at this point if the APR actually provides what needs to
be provided. That will likely be thoroughly investigated before long.
