pandoc is seriously under-powered for the kinds of things that LaTeX and Typst can do. Much of the information in Typst/LaTeX source code would simply be ignored during the conversion. It is fine for simple documents, but cannot handle a lot of stuff.
Pandora offers a superset of LaTeX and any other markup languages as long as you’re not using it for final rendering. I have a Markdown+LaTeX project I’m working on and try to write mostly in markdown, but can drop down into LaTeX in-line if need be. I compile a tex file with Pandoc and render with pdflatex, bibtex, makeindex, etc., etc.
This is not the workflow being discussed. Yes, you can use Pandoc Markdown (in which you can embed LaTeX) and then Pandoc can parse the markdown and produce a LaTeX file. But the actual typesetting is still done by LaTeX; here Pandoc is basically just a preprocssing step.
what was being discussed is using Pandoc to convert from Typst to LaTeX, which it can't really do because its internal document representations are not as expressive as either Typst or LaTeX.
