References

References

References substitute reusable object patterns into other definitions. The referenced object's variables are merged into the parent — without creating a child relationship.

Loading

Key: Referenced objects do not appear as children. Only their variables are merged.

Syntax

<-{ refA, refB ... }->

References cannot be empty.

---

Example

Define reusable parameter types:

<:string:> string <<var>> <:>
<:int:> int <<var>> <:>

Use them as references in a function definition:

<:function:> function <<name>> ( <-{string, int}-> ) { <---> } <:>

The function can accept string or int parameters. The <<var>> variable from each referenced object is added to the function's variable set.
