</div>You're more likely to understand the core ideas in Racket from the<br>
paper "Macros the Work Together" (by Matthew and others), which<br>
describes how the algorithms as implemented in Racket work. This is<br>
somewhat different from Dybvig's paper, and both are much different<br>
than "Macros that Work". Also, I think Matthew's paper is much easier<br>
to understand.<br>

That is quite an enlightening read. Thanks for the pointer, Sam.</div></div><br></div></div>
