* sick should use a standard (for INTERCAL values of "standard") grammar
  to parse its (mis)configuration file, say "sickrc.io"
* regular grimaces (INTERCAL's answer to regular expressions); currently,
  support for regular grimaces is included in the compiler, but
  cannot be used until somebody writes the module. To do pattern matching,
  one would use a regular grimace in a CREATE statement, then try to
  execute a comment to trigger the new grammar production; this is probably
  quite unlike what other languages do. It should be added that it is
  already possible to do pattern matching using pseudo context-free
  grammars by using the CREATE statement without regular grimaces. You
  didn't really want to know that, did you?
* C backend which generates C code to be compiled with your normal C compiler.
