Why is this an issue?

Shared naming conventions allow teams to collaborate effectively. This rule raises an issue when a local variable or function parameter name does not match the provided regular expression.

Noncompliant code example

With the default regular expression ^[_a-z][a-zA-Z0-9]*$:

public function doSomething(my_param:int):void
{
  var LOCAL:int;
  ...
}

Compliant solution

public function doSomething(myParam):void
{
  var local;
  ...
}
