It would be good to see a comparison of metaprogramming with macros. They

From what I can tell the difference seems to be that it goes inside the

even if the function call results in a string.
This behaviour seems really strange. I feel like maybe there's some

For the Java libraries, I like Java Cookbook 2ed by Ian Darwin. It
doesn't spend much time on the language. It includes introductions to
Swing, network clients and servers, regular expressions,
introspection, and JDBC. It was published in 2004, so it doesn't cover
Java 6.

There could be a strict mode versus an optimized mode.
That could allow more optimizations at run time while

I like the sequential let too. For one thing, it allows for the
breaking apart of complex expressions into more comprehensible parts,
with well named intermediate variables resulting in self documenting
code. For another, if a calculated value is used more than once, then
