``!getdagop(``\ *dag*\ ``)`` --or-- ``!getdagop<``\ *type*\ ``>(``\ *dag*\ ``)``
This operator produces the operator of the given *dag* node.
Example: ``!getop((foo 1, 2))`` results in ``foo``.
Example: ``!getdagop((foo 1, 2))`` results in ``foo``. Recall that
DAG operators are always records.

The result of ``!getdagop`` can be used directly in a context where
any record class at all is acceptable (typically placing it into
another dag value). But in other contexts, it must be explicitly
cast to a particular class type. The ``<``\ *type*\ ``>`` syntax is
cast to a particular class. The ``<``\ *type*\ ``>`` syntax is
provided to make this easy.
For example, to assign the result to a value of type ``BaseClass``, you
could write either of these::
BaseClass b = !getop<BaseClass>(someDag);
BaseClass b = !cast<BaseClass>(!getop(someDag));
BaseClass b = !getdagop<BaseClass>(someDag);
BaseClass b = !cast<BaseClass>(!getdagop(someDag));
But to create a new DAG node that reuses the operator from another, no
cast is necessary::
dag d = !dag(!getop(someDag), args, names);
dag d = !dag(!getdagop(someDag), args, names);
``!gt(``\ *a*\ `,` *b*\ ``)``

``!setop(``\ *dag*\ ``,`` *op*\ ``)``

This operator produces a DAG node with the same arguments as *dag*, but with its

Example: ``!setop((foo 1, 2), bar)`` results in ``(bar 1, 2)``.
Example: ``!setdagop((foo 1, 2), bar)`` results in ``(bar 1, 2)``.
