I expected the following to be equivalent:
Function call sytnax:
Method call syntax:
The function call outputs:
The method call outputs an error:
In the latter, $x is the array without being unfolded.
Note: I could not find a workaround in the syntax to be able to splat for a method call.
probability: low (unfolding IN arrays/method calls/etc)
severity: medium (no work arounds other than using different class function structure)
test layer: unit
