It would be nice to have support for blocks that evaluate, but do not produce any markdown output.

I'm writing some tutorial for a library in mdx, and need to have a snippet of code of 20-30 lines to present to the reader. Writing it in toplevel block directly is not very convenient as it won't get automatically formatted. Making it a file block solves the problem of formatting, but the code is not evaluated in mdx context. My best approach so far it to load it into toplevel via #use directive, but it outputs a lot of signatures along the way. Once loaded, I can present separate sections of the file via file blocks and then show some toplevel evaluation of the constructs defined in the file. With silent block I could load it without extra noise in the markdown output.
