Sounds reasonable to me, but I don't have much experience using the delay equation interface (so don't know how general it is or what we'd want to support). I guess...

Sorry, I'm not sure I understand your question. Can you be more precise about what you want to do (i.e. give some example code or write it out mathematically)? I'm...

With https://github.com/SciML/Catalyst.jl/pull/423, we have flattening of systems and can start to think about this. I think it makes sense to look at in two-steps: 1. Support simple equations like `sys1.A...

We’d at least need a base unit specified for time and amount of a species. But the usefulness of units currently is we can check combinations of parameters don’t give...

I don't think we have any `SteadyStateProblem` or `NonlinearProblem` examples currently. Are `SteadyStateProblem`s recommended anymore, or should we just be pointing towards `NonlinearProblem`? @yewalenikhil65 are you advocating for making the...

We have an untested conversion to NonlinearProblem at https://github.com/SciML/Catalyst.jl/blob/8e3e05c6d1d501c8994bcdee471cd2a19ea2e6b3/src/reactionsystem.jl#L476 but it doesn’t appear to drop any time dependence from states or equations.

If you want to put in a PR that makes the parsing code more modular that would be great and appreciated! It would need some work to generate `Reaction`s from...

Certainly! Making it more modular would be great. We've also recently discussed adding a ```julia rx = @reaction k, A --> B ``` type macro, so having a standalone parser...

We regards to those two, we would like to head towards allowing spatial structures, so including compartments in some way would ultimately make sense. I'm not sure if the best...

The units are whatever the user's parameters, initial condition, and time variable implicitly define when they construct the concrete problem type. I just tried a couple examples with homodimerization reactions...
