Hmm, I disagree with this pretty strongly. From a debugging perspective, I
want the source templates available, at least optionally, in addition to
the resulting R code.
Also, while not on the CRAN team, large amounts of code generation during
.onLoad seems liek it would be out of bounds, as I'm pretty certain that
would bypass all of the R CMD check tests, which seems like it would be a

It does work now, I think, but I may get back to it and do some more. If
you take a look, definitely let me know what you think and if you feel like
anything is missing/could do with a different approach/syntax in your
opinion. Great to hear that . someone is interested in it, that's
certainly motivating :).
