============================

printf
|
||
|
|
|
||
|
|
`~&`, `sigpam`, is a synthetic rune that prints `q` on the console
|
||
|
|
before computing `r`. `p` is the log priority, 0-3 defaulting to 0. `~&`
|
||
|
|
is similar to `printf` or `log` in other languages, and is very commonly
|
||
|
|
used for debugging.
