This doesn't work when assigning to a context variable and I would like it to:

{%- macro mymacro(testarg) -%}

Arg: {{ testarg }}

{%- endmacro -%}

{{- mymacro -}}

End goal is for me to be able to call {{ CTX.mymacro(arghere) }} later in my workflow without having to define it on every step.

Looks like this will need a JSON serializer written for macros in order for it to work.
