It's clear that passing in arbitrary objects is not feasible. But what if I'm prepared to constrain input to built-in numeric and string types, possibly in or with nested dicts?
In many cases the input will be large integer or float arrays, and I want to avoid any nasty
kludge such as printing those inputs into the top lines of the src ;). The src in the demo is a constant,
but in the application, it's provided by users via a list of pre-defined and user-created 'macros'.
If I'm missing something obvious, flames welcome!
