E0716: A Go file the folder's package can't hold
The go command builds no [id] folder and no route group (admin): an import path can hold neither a bracket nor a parenthesis. vuka compiles such a folder where the go command sees it, param_id/ or group_admin/, its .vuka and .vuka.html files' Go and its own .go files together, as one package. A private folder below pages/ holding Vuka source, _parts, is compiled the same way, as private_parts/.
Two things can't be: a .go file whose package clause names another package than the folder's other files (only the external test package, name_test, may differ), and a .go file named for a parameter, [id].go, which the go command reads nowhere. Reported at the file.
