This isn't something that really works, as we can't compile language X into code that we can execute to evaluate an expression.

I don't think we can wholesale disable the debug console input when in WASM locations, but we could print some more helpful error message.

I kind of wasn't expecting it to work, what confused me the most was it was saying b was a thing

It looks like we actually can evaluate some expressions and the DWARF debugger includes lldb-eval. So we just need to delegate execution there, and complex expressions will error appropriately. Should be easily enough.

@joyceerhl can you confirm the DWARF debugging extension is installed and enabled, and if so set trace: true and share your logs?

Works well, I forgot I'd disabled it for verifying another issue 🤦
