If you want good results with intellisense/omnicomplete you need sigs. Steep does some type synthesis but giben Runy's very dynamic nature it's going to be hit and miss, so that's mostly for progressive typing. It really aims at leveraging static information.

The process is basically `rbs prototype` or `typeprof` to generate a sig file and steep then uses that. TBH it's not that much of a chore as it sounds and already gives you good-ish results. That gives you a bunch of material to work from and progressively refine types.

Speed is very good, I didn't notice anything slow.

For context, the reason I ask is that I am developing some Ruby gems, and considering whether it's worth adding .rbs files.

In the Python libraries I maintain, types are useful to anyone who installs the default Python VS Code plugin, because it gives them intellisense (but doesn't give them red squiggly lines for type errors) even if they do nothing to set up types or a typechecker.

Is that or will that be the case for Ruby/Steep?
