------------------------------------------
Summary: Permit spread operator in static mode for varargs
Key: GROOVY-10597
URL: https://issues.apache.org/jira/browse/GROOVY-10597
Project: Groovy
Issue Type: Improvement
Components: Static Type Checker
Affects Versions: 4.0.2
Reporter: Christopher Smith
I have a varargs method that takes many parameters for inclusion into an output
JSON array. I am needing to preprocess some of these parameters, and I tried to
use the spread operator to deconstruct them inline. However, I'm receiving the
error "The spread operator cannot be used" because the compiler can't determine
arity.
This is perfectly sensible, but in the specific case where the spread operator
would be applied in a position where its values expand into a varargs, as long
as the element type produced by the spread is a subtype of the declared varargs
type, it would be helpful for the spread to succeed.
