--parser typescriptInput:
type Test<T> = T extends ((
token: TSESTree.Token
) => token is infer U extends TSESTree.Token)
? U
: TSESTree.Token;Output:
type Test<T> = T extends (
token: TSESTree.Token
) => token is infer U extends TSESTree.Token
? U
: TSESTree.Token;Expected behavior:
The parentheses should be retained as they are required.
Without the parentheses it causes a syntax error:
SyntaxError: '?' expected. (5:19)
