Debug "macros" (dbg! in templates)

[Tamschi]

There currently isn't an easy way to inspect a component in the browser. Supporting a dbg!-like syntax that resolves into an HTML comment would provide a first avenue in this direction.

Writing dbg!{value} if value is e.g. "five" should result in a comment like <!-- value = "five" -->, using pretty Debug formatting.

Alternative options I considered are hooking into tooling for certain JavaScript frameworks, looking for browser tooling hooks or even writing my own inspector integration. However, for now all that would lead to considerable implementation effort compared to outputting plain comments.
