Lines 135 to 140 in d57112d

	oauthParams = { auth, params }:

in nix-repl --expr 'import <nixpkgs> {}' shows that

       error: value is a function while a list was expected

while parenthesizing the second argument works:

nix-repl> "?" + builtins.concatStringsSep "&" (lib.attrsets.mapAttrsToList (k: v: k + "=" + lib.strings.escapeURL v) {"a" = "b"; "c" = "d";})
"?a=b&c=d"
