Mojo doesn't have C++-like exceptions, but does support throwing. The codegen approach is basically like go's (where you return a bool + error conceptually) but with the python style syntax to make it way more ergonomic than Go.

We have a public roadmap and are hard charging about improving the language, check out https://docs.modular.com/mojo/roadmap/ to learn more.
