How do I pass a dict to a def when it's called from <%namespace:def>.
I would expect that calling
<%namespace:def param="${ {'id':123} }"></namespace:def> to work, but when I do I get an error saying I am missing a closing }
for reference <%call expr="namespace.def(param={'id':123})"></%call> works as expected.
