meshed operations

[thorwhalen]

Historically, I've gotten a bit of resistance from software developers when I venture towards the desire to add some "operator interfaces" to some functionality. Method chaining seems to be more easily excepted, yet if I start involving > and | operators, I get some frowns.

Thus, in meshed, I've discretely added an __add__ (and __radd__) operator, but not really advertise it much.

Being involved in LLMs currently, I ran into the description of the LangChain's Expression Language (LCEL) and realize this could very much fit in a description of "why meshed" and "why gurgle" (project that was meant to use facilitate adding trackers etc. to meshes).
Mesh wants to go being linear chains, but besides that, it has a lot of what LCEL is describing.

Since LangChain is so popular, maybe it's okay to include operators in meshed?
