10We've found it's useful to have a quick reference of Hoon's syntax always at
11hand. So above is a download link to a Hoon cheatsheet .pdf. It's missing a
12few of the literal syntaxes, but it covers the most common ones.
14This doesn't list any of the Ford runes, although there is now at least
15some documentation for those [here](@/docs/tutorials/arvo/ford.md).
17The following runes also exist, but are currently undocumented and not listed in
18the cheat sheet:
20```
21!: :: turn on debugging printfs
22!. :: turn off debugging printfs
23!; :: using the "type of type", emit the type for an expression
24!, :: emit AST of expression
25$* :: bunt (irregular form is *)
26^. :: use gate to transform type
27^& :: zinc (covariant) -- see the docs on advanced types
