# and/or https://github.com/comfyanonymous/ComfyUI/pull/1503 is pulled into ComfyUI, we need a way
# to optimize the recursion that happens on prompt eval. This is particularly important for
# rgthree nodes because workflows can contain many context nodes, but the problem would exist for
# other nodes' (like "pipe" nodes, efficieny nodes). With `Context Big` nodes being
# introduced, the number of input recursion that happens in these methods is exponential with a
# saving of 1000's of percentage points over.
