Optimized Python side

[stefnotch]

Future optimizations would be knowing all the different Python functions that can get called and having "callbacks" for them instead of using pyodide.runPython. Basically, executing actual functions instead of eval-ing code. Relevant

• https://github.com/iodide-project/pyodide/blob/76efcaccf7cb0f478ed1f17fd36cd79f3370980e/src/pyproxy.c#L97
• Directly calling things like Module.hiwire_new_value and Module.__pyproxy_apply
• https://github.com/iodide-project/pyodide/blob/fc5495ffdb54a11fd588dc60ba6b8777f90c3724/src/python2js_buffer.c#L458

Another potential optimization would be using bytes and buffer objects for larger values, as those don't have to be copied in memory.

Also, keep track of other projects like

• https://github.com/RustPython/RustPython
