Why is boolean value f (false) defined as a parsing-word while t (true) is not? [Factor programming language]
I noticed when attempting to generate random booleans that `t` and `f` are not treated in the same way:

```factor
t random ! Error
f random ! returns a value
```

In the factor 0.98 and 0.99 documentation, [`t`](https://docs.factorcode.org/content/word-t,syntax.html) is defined as a simple word, whereas [`f`](https://docs.factorcode.org/content/word-f,syntax.html) is given special status as a parsing word. Why?
