Enso is super cool, been following their work since the time they were called luna :) Flyde is TS to start with, but Python is the next candidate in language support. Eventually, the plan is to rewrite the core/runtime layer of Flyde to a more performant language (Rust/Go) and enable interoperability, so you could potentially even mix and match node implementations. One node could be built with Python, the other with JS, and the flow itself will be agnostic to it.
