Many filetypes from filetype.vim set buffer-local variables, meaning vim.filetype.match cannot be used without side effects. Instead of setting these buffer-local variables in the filetype detection functions themselves, have vim.filetype.match return an optional function value that, when called, sets these variables. This allows vim.filetype.match to work without side effects.
