* Represents the logical implication combinator for predicates. In formal

* logic, the implication operator `->` denotes that if the first proposition
|

* (antecedent) is true, then the second proposition (consequent) must also be
|
||
* true. In simpler terms, `p implies q` can be interpreted as "if p then q". If
|
||
* the first predicate holds, then the second predicate must hold
|
||
* for the given context.
|
||
*
|
||
* In practical terms within TypeScript, `p implies q` is equivalent to `!p || (p && q)`.
|
||
*
|
||
* Note that if the antecedent is `false`, the result is `true` by default
|
||
* because the outcome of the consequent cannot be determined.
|
||
*
|
||
* This function is useful in situations where you need to enforce rules or
|
||
* constraints that are contingent on certain conditions.
|
||
* It proves especially helpful in defining property tests.

* `implies` function. In simple terms, if `a <= b` and `b <= c`, then `a <= c`
|

* must be true.

|
||
* ```ts

* import * as assert from "node:assert"
