* This can't work for two reasons:
- * -SENF_PARSER_PRIVATE_VARIANT only accepts 6 templates in types but you have to start from 0.
- * -you NEVER can use templated Parsers in these macros since the macro-preprocessor won't recognize the <> brackets and will
- * interpret the ","

+ * -you NEVER can use templated Parsers in these macros since the macro-preprocessor won't recognize the <> brackets and will

*
- * The first problem is solved by using (actually inventing) SENF_PARSER_VARIANT_TRANS which has the same limitations
- * concerning the number of types but isn't limited to the values used. This is achieved by a translating function
- * as you can see.
+ * The first problem is solved by using key()

- * templates have to be used.
