* sick should use a standard (for INTERCAL values of "standard") grammar
2
to parse its (mis)configuration file, say "sickrc.io"
3
* regular grimaces (INTERCAL's answer to regular expressions); currently,
4
support for regular grimaces is included in the compiler, but
5
cannot be used until somebody writes the module. To do pattern matching,
6
one would use a regular grimace in a CREATE statement, then try to
7
execute a comment to trigger the new grammar production; this is probably
8
quite unlike what other languages do. It should be added that it is
9
already possible to do pattern matching using pseudo context-free
10
grammars by using the CREATE statement without regular grimaces. You
11
didn't really want to know that, did you?

* C backend which generates C code to be compiled with your normal C compiler.
