... which means that you can use that at the context end as well (old feature).
Save the following as test.mkix (or add "% macros=mkix" as the first line):

```
\starttext
<?lua if tex.modes["A"] and not tex.modes["B"] then ?>
\starttyping
A and not B
\stoptyping
<?lua else ?>
\starttyping
not (A and not B)
\stoptyping
<?lua end ?>
\stoptext
```

See the templates manual for more details: https://www.pragma-ade.com/general/manuals/templates-mkiv.pdf
