do not crash on syntax errors

Right now if I have an app running and I change the Python source, it reloads, and with client-side hot-reloading the experience is really awesome. But. If I make an error in my Python, the whole loop crashes and I need to go to my terminal to restart the app.

The ideal workflow from my perspective would be for the app to try to reload, and if there's a Python error, it would tell me on the console and then not exit but rather keep watching the file and if I re-save, it would load the file again, such that I could just look at my console, fix the error and resave, without having to leave my editor.

@T4rk1n @rmarren1 any thoughts on the feasibility of this?

Empieza localizando el bucle de recarga del código fuente de Python y su gestión de los fallos de recarga. Reproduce el problema guardando un error de sintaxis en una aplicación en ejecución; después, verifica que el error se informe en la consola, que el proceso siga activo y que un guardado posterior vuelva a intentar la recarga.
