Research direction

No source file or test is named. Start by reproducing the shown C# traversal and compare FunctionTemplate.Specializations with ClassTemplate.Specializations for the same parsed input. Done means determining whether function-template specializations should be populated and either correcting that behavior or clearly documenting the limitation.

Description

Brief Description

How can I get function templates specializations (similar to class templates specializations)?
I am using the following code:

            foreach (var template in sourceUnit.Templates)
            {
                if (template is FunctionTemplate ft)
                {
                    foreach(var specialization in ft.Specializations) // always ft.Specializations is empty !!!
                    {
                    }
                }
                else if (template is ClassTemplate ct)
                {
                    foreach (var specialization in ct.Specializations) // ct.Specializations gives back the correct results !!!
                    {
                    }
               }
               else if (template is VarTemplate)
               {
               }
               else if (template is TypeAliasTemplate)
               {
               }
               else
               {
               }

Kind regards,
