The macro just creates the `for` expression. If you need to put the for expression inside a block then the macro needs to accept the body of the for too. Do C macros allow passing a code block?

Yes. You can pass pretty much whatever you want so long as parenthesise match and there is no comma outside of parenthesise.

The comma is a bit of a huge pita if you're passing a whole loop body.
