 This is the final submission for a compiler course I took from <a
 href="http://en.wikipedia.org/wiki/R._Kent_Dybvig">Kent Dybvig</a> at Indiana
 University. The compiler compiles a significant subset of Scheme into X64
-assembly and then linked with a runtime system written in C. I made attempts to
-simplify and innovate the compiler, so it is quite different from Kent's
+assembly and then links it with a runtime system written in C. I made attempts
+to simplify and innovate the compiler, so it is quite different from Kent's
 original design.
 
 In Kent's words, I put myself into trouble each week by doing things differently
 and then get myself out of it. Sometimes I did better than his compiler,
 sometimes, worse. But eventually I passed all his tests and got an A+.
 
 A notable thing of this compiler is its use of _high-order evaluation contexts_,
-which resulted sometimes in much simpler and shorter code. The same technique is
-used in <a href="https://github.com/yinwang0/lightsabers/blob/master/cps.ss">CPS
-transformers</a>.
