This feature request is for a node that is able to accept Python code.
Instead of accepting different input types, (such as lists etc) it may be really useful to simply allow this node to parse Json, as a way of controlling composition flow, etc.
Considering that Python would not be fast enough, (pure Python) for image / audio processing, using Python as a control language for Vuo could make more sense.
There are already many tools within Python to work with Json already, so this could be very useful as IIRC that Vuo already uses Json as the format to connect nodes together?
Also there are many external libraries (such as NumPy) that do allow fast processing of data, so possibly we could access different types of Vuo data simply from the Json string?
