What is the preferred syntax for simple on/off states? Did I

true/false on/off yes/no?
If so, is there an idiom for yes/no/maybe -1,0,1
less/equal/greater?
Excuse the noise. For some backfill; getting used to DDoc.
Frontmatter can be attached to the module declaration. Great
for setting up a page. Wanted to do something similar for
backmatter, in particular the without warranty disclaimer
(instead of it taking up space on the first screen of a
listing). That means attaching backmatter doc comments to a
declaration, something akin to `enum INDEMNITY = true;`. Or is
it `= 1`?
Opinions welcome, as this will end up being nothing more than a
personal preference, but it would be nice to avoid dragging
fingernails over anyone's mental chalkboard.
Have good, make well.
AFAIK, the usual wisdom is to use `true` or `false` over `1` and
`0`.
However, it still might not be enough in a public API, so there
is `std.typecons.Flag`:
https://dlang.org/library/std/typecons/flag.html
Last but not least, `true` is defined as `1` per the spec, so the
following is valid:
```
char[] myString = getString();
bool hasNullCharAtEnd = parseString(myString);
char[] copy = new char[](myString.length - hasNullCharAtEnd);
```
This is quite useful when needed to offset something by one: Just
add or subtract your `bool` value.
