Pulling
|
||
|
|
-------
|
||
|
|
|
||
|
|
The `%` runes [pull]() [`++arms`]() and [`++wings`]() from the
|
||
|
|
[subject](), often modifying their values. The `%` runes are similar to
|
||
|
|
function calls, or execution tools. We use them to either compute some
|
||
|
|
code with changes in the subject, or produce the output from a core.
|
||
|
|
|
||
|
|
There are two categories of `%` runes.

#### Pull with changes:
|
||
|
|
|
||
|
|
[`%=`]() The natural `%` rune. Evaluates `p` with the changes specified
|
||
|
|
in `q`.
|
||
|
|
|
||
|
|
[`%_`]() Evaluates `p` with the changes specified in `q`, then
|
||
|
|
casts the product back to the type of `p`.
|
||
|
|
|
||
|
|
[`%*`]() Evaluates `p` from a [door]() `q` with changes `r`.Terminated by `==`.

### Pull the empty arm `$`, similar to calling a function:
|
||
|
|
|
||
|
|
[`%-`]() [slams]() a core with one argument.
|
||
|
|
|
||
|
|
[`%+`]() slams a core with two arguments.
|
||
|
|
|
||
|
|
[`%^`]() slams a core with three arguments.
