// Inherit, macro: new_child_parse
// -------------------------------
// Inheritance is implemented with this macro. It is also used for the inheritance
// of the application itself.
//
//
// Block level scope example:
//    {:code; <--------------------------.
//        {:* block *:}                  |<---- Block
//        {:param; name >> value :} <----|----- Set "name" for this block and its children
//        {:param; name :} <-------------|----- "name" has the value "value".
//        {:code;                        |
//            {:* child block *:}        |
//            {:param; name :} <---------|----- "name" has the value "value".
//        :}                             |
//    :} <-------------------------------ยท
//    {:param; name :} <----------------------- outside block, no value or a previous value if any.
//
//
// "include" has a block scope, then:
//    {:code;
//        {:* include for set "snippet-name" *:}
//        {:include; snippet.ntpl :}
//        {:snippet; snippet-name :} {:* Ok, "snippet-name" is set *:}
//    :}
//    {:snippet; snippet-name :} {:* Ko, "snippet-name" is not set *:}
//
// The modifier scope (+) adds the scope to the current level to make it possible to do this:
//    {:+bool; something >>
//        {:include; snippet.ntpl :}
//    :}
//    {:snippet; snippet-name :} {:* Ok, "snippet-name" is set *:}
//
