+
+### @compileLog(args: ...)
+
+This function, when semantically analyzed, causes a compile error, but it does
+not prevent compile-time code from continuing to run, and it otherwise does not
+interfere with analysis.
+
+Each of the arguments will be serialized to a printable debug value and output
+to stderr, and then a newline at the end.
+
+This function can be used to do "printf debugging" on compile-time executing
+code.
