Description

Follow up to GROOVY-6668. Explicit getAt call produces different error from square-bracket version. Could they both produce the same error? I prefer "Cannot call ... with arguments [groovy.lang.GString]" over the recently introduced "Cannot find matching method ..."

@groovy.transform.CompileStatic
void meth() {
  def key = "${'key'}"
  Map<String, String> map = [:]

  map[key].toUpperCase() // Cannot find matching method java.lang.Object#toUpperCase(). Please check if the declared type is correct and if the method exists.
  map.getAt(key).toUpperCase() // Cannot call <K,V> java.util.LinkedHashMap <java.lang.String, java.lang.String>#getAt(java.lang.String) with arguments [groovy.lang.GString] 
}

It appears that the square-bracket version may have selected extension method static Object getAt(Object self, String property).
