| ### Alternative to Union Types | ||
| As shown, union types can be used to represent alternatives of several different types, without requiring those types to be part of a custom-crafted class hierarchy, or requiring explicit wrapping. | ||
|
|
||
| #### Pre-planning the Class Hierarchy | ||
| Other languages would require pre-planning of the class hierarchy, like the following example illustrates: | ||
|
|
||
| {% tabs union-preplanning %} | ||
|
|
||
| {% tab 'Scala 3 Only' %} |
There was a problem hiding this comment.
Suggested change
| {% tab 'Scala 3 Only' %} | |
| {% tab 'Scala 2 and 3' %} |
