+## Test code with syntax errors
+
+Syntax errors aren't handled well yet - the result is almost always a
+single message about the first error. So this section will be fairly
+thin until we add proper parsing recovery in the face of common errors.
+
+A special case of syntax errors is token errors, when a token is only
+accepted because the parser doesn't know quite enough to reject it.
+There are handled better as they are quite local, so a single test
+program can trigger most of the possible errors.
+
+To handle erronous code, we need a different set of tests, as we need to
+capture `stderr`. The same test code will be used for type errors too.
+As error messages contain the line number, and we don't want changes to
+this file to change the reported numbers, we copy the code into a
+separate file first, then run from there.

+## Tests for type errors
+
+Type error don't cause parsing to abort, so we can fit many in the
+one test program. Some type errors are found during the parse, others
+during type analysis which doesn't run if parsing failed. So we cannot
+fit everything in one.
+
+These programs were generated by looking for the
+various places that `type_err()` are called.

+## Test erroneous command line args
+
+To improve coverage, we want to test correct handling of strange command
+line arguments. These tests won't use code, so the exiting test types
+won't work. So we need to be able to explicitly give the command line,
+and the expected output, and have that tested and the coverage assessed.
+Rather than having to spell out the whole command name, just give "cmd",
+and discard that. Requiring but discarding the command make an empty
+command list possible.
