Product as subject, inverse
=<
is a synthetic rune that uses the product of q
as the subject of
p
. =<
is the inverse of =>
. Use =<
when your computation, q
is
lengthier and =<
makes for more readable code.

Produces
Twig: [%tsgl p=twig q=twig]
Sample
p
and q
are twigs.
Tall form
=< p
q
Wide form
=<(p q)
Irregular form
p:q
Examples
~zod/try=> b:[a=1 b=2 c=3]
2
~zod/try=> [. .]:(add 2 4)
[6 6]
In this simple example we first produce b
from the tuple
[a=1 b=2 c=3]
using the irregular form of =<
. Then we use .
to
produce our context from the computation (add 2 4)
as a cell, [6 6]
.
~zod/try=> =< lom
|%
++ lom (add 2 tak)
++ tak 4
--
6
This example is a more common case, where we want to pull some specific
value out of a longer computation. Here we use the tall form of =<
to
pull the arm lom
from the core created with |%
.
