**(either: // ...Any//) -> //Any//**

Give this macro several values, separated by commas, and it will pick and return
one of them randomly.

=== Example usage: ===

''%%A (either: "slimy", "goopy", "slippery") puddle%%'' will randomly be "A slimy puddle", "A goopy puddle"
or "A slippery puddle".

=== Rationale: ===

There are plenty of occasions where you might want random elements in your story: a few random adjectives
or flavour text lines to give repeated play-throughs variety, for instance, or a few random links for a "maze"
area. For these cases, you'll probably want to simply select from a few possibilities. The (either:)
macro provides this functionality.

=== Details: ===

As with many macros, you can use the spread ''%%...%%'' operator to place all of the values in an [[harlowe:array|array]] or [[harlowe:dataset|dataset]]
into (either:), and pick them randomly. ''%%(either: ...$array)%%'', for instance, will choose one possibility from
all of the array contents.

If you want to pick two or more values randomly, you may want to use the [[harlowe:shuffled|(shuffled:)]] macro, and extract a subarray
from its result.
