barlus, `|+`, %brls

%iron gate

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

Produces

Twig: [%brls p=tile q=twig]

Sample

p is a tile. q is a twig.

Tall form

|+  p
    q

Wide form

|+(p q)

Irregular form

None

Examples

~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)))
32

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