An video of me invoking go to definition on a reference to a function defined within a macro, causing VSCode to open the macro expansion as a virtual buffer putting the cursor on the definition within the expansion followed up by me invoking go to definition on the stringify token in that virtual buffer causing VSCode to go to the definition of stringify in the standard library
A gif of me invoking go to definition on a function defined within a macro resulting in VSCode showing a peek window of the definition within the virtual macro expansion file instead of going to the macro definition
