/**
* This method serves as an entry point for the content assist scoping for simple feature calls.
*
* @param context the context e.g. a for loop expression, a block or a catch clause
* @param reference the reference who's value shall be scoped. Not necessarily a feature of the
* context.
* @param includeCurrentBlock <code>false</code> in the context of scoping but content assist will
* not have the actual value holder of the reference at hand so it passes its container to
* this method and expects the declared variables to be exposed in the scope.
* @param idx the index in an expression list of a block. Otherwise to be ignored.
