## Basic tests
Some simple tests... maybe all tests are simple.
+Include a special test for numbers, as they are interesting.

+## Nested tests.
+
+We need to test various aspects of tokenizing code that is stored
+in multiple nodes. For example, comments and multi-line strings mustn't
+cross a node boundary.
+
+For this we tell `scanner` to extract sections directly from this file.
+As the file changes, line numbers might change as well, so we need to factor
+that out when testing. A simple awk script can normalise the first line number
+to one.
+

+## Ad-hoc test
+
+These tests test bugs that were found in practice, and so prevent them recuring.
+
+The "bad_indent" test was written because I was seeing a TK_in before the
+"program" instead of TK_newline
