**(link-repeat: // [[harlowe:String|String]]//) -> //[[harlowe:Changer|changer]]//**

Makes a [[harlowe:changer|changer]] to create a special link that shows a hook, and, when clicked again,
re-runs the hook, appending its contents again.

=== Example usage: ===

''%%(link-repeat: "Add cheese")[(set:$cheese to it + 1)]%%'' will create a link reading "Add cheese"
which, when clicked, adds 1 to the $cheese variable using [[harlowe:set|(set:)]], and can be clicked repeatedly.

=== Rationale: ===

This is similar to [[harlowe:link|(link:)]], but allows the created link to remain in the passage
after it is clicked. It can be used to make a link that displays more text after
each click, or which must be clicked multiple times before something can happen (using [[harlowe:set|(set:)]]
and [[harlowe:if|(if:)]] to keep count of the [[harlowe:number|number]] of clicks).

=== Details: ===

This creates a link which is visually indistinguishable from normal passage links.
Each time the link is clicked, the text and macros printed in the previous run are
appended.
