== Why is this an issue? {upper_function}s with a long parameter list are difficult to use because maintainers must figure out the role of each parameter and keep track of their position. include::{language}/noncompliant.adoc[] The solution can be to: * Split the {function} into smaller ones include::{language}/split-example.adoc[] * Find a better data structure for the parameters that group data in a way that makes sense for the specific application domain include::{language}/struct-example.adoc[] This rule raises an issue when a {function} has more parameters than the provided threshold.
