[BUG] Debugging experience is very poor about denopack HOT 4 OPEN

I see two ways to fix this:

• stop including the minified version of Rollup, and use the clear one instead
• encourage Rollup developers to include a source-map in the bundle (I'm not sure if Deno supports source maps?)

this is surely an issue for Rollup - it ought to be simple for them to add a sourcemap to the browser output file (I'm not sure how much the browser file is actually used).

Deno supports V8 Inspector (I often use the inspect-brk option), though I think you have to use deno run - I don't think it works as an option on the installed denopack.

It may be a Rollup issue, yes. Good point.

FYI I have raised an issue for the particular error you reference above rollup/rollup#3934 and a PR to fix rollup/rollup#3935 in the Rollup project. Doesn’t help with the debugging aspect of this issue, but may provide some more context what the error is, why it occurs and hopefully a path forward towards fixing it.
