[barlus, `|+`, %brls](#brls)
|

|
|
============================
|
||
|
|
|
||
|
|
`%iron` gate
|
||
|
|
|
||
|
|
`|+` is a synthetic rune that produces a [dry]() [`%iron`]() [gate]()
|
||
|
|
with sample [`$*(p)`]() and [arm]()s `q`. `|+` is similar to `|=`, but
|
||
|
|
differs in that its sample cannot be read. It can be thought of as
|
||
|
|
similar to a private function.

|
|

|
|
~zod/try=> +<:|+(a=@ a)
|

|
|
! -axis.6
|
||
|
|
! peek-park
|
||
|
|
! exit
|
||
|

~zod/try=> +<:|=(a=@ a)
|

|
|
a=0
|
||
|
|
|
||
|
|
Here we're trying to read the sample, using `+<` of two different kinds
|
||
|
|
of gates. With `|+` you can see we cause an error, whereas with `|=` our
|
||
|
|
default sample is `a=0`.
|
||
|
|
|
||
|
|
~zod/try=> %.(20 |+(a=@ a))
|
||
|
|
20
|
||
|
|
~zod/try=> %.(20 |=(a=@ a))
|
||
|
|
20
|
||
|
|
~zod/try=> %.(20 |+(a=@ (add a 12)))
|

Kicking a `|+` gate, however, is the same as `|=`.
