Ƒ - Invariant
Tags: boolean , hyper
The resulting link's arity depends on the consumed links, but will be of fixed arity when returned. This is different from variadic links, whose arity can change or be coerced by context or other quicks. Note that the arity refers to that of the resulting link, not the number of links this quick consumes.
Check if the left argument is equal to the result.
0Ƒ is equivalent to
⁼0$. For monads,
AƑ is equivalent to
⁼A$. For dyads,
×Ƒ is equivalent to
<nilad>Ƒ- a monadic link that checks if the left argument is equal to
<link>Ƒ- a link of the same arity as
<link>that checks if the left argument is equal to the result of the link
