你做了什么？

// FirstFollowConflictError is a first/follow LL(1) grammar parse conflict.
type FirstFollowConflictError struct {
	Nonterminal string
	// An [Identifier] or [Literal]
	Terminal any // an [Identifier] or [Literal]
}

$ go doc FirstFollowConflictError

你期望看到什么？

package ebnf // import "."
type FirstFollowConflictError struct {
	Nonterminal string
	// An Identifier or Literal
	Terminal any // an Identifier or Literal
}
    FirstFollowConflictError is a first/follow LL(1) grammar parse conflict.

你实际看到了什么？

package ebnf // import "."
type FirstFollowConflictError struct {
	Nonterminal string
	// An [Identifier] or [Literal]
	Terminal any // an [Identifier] or [Literal]
}
    FirstFollowConflictError is a first/follow LL(1) grammar parse conflict.

注意上面和旁边的Terminal字段周围的方括号。它们没有被解析和呈现为文档链接。如果将它们放在类型声明上方，括号就会消失，如预期的那样。
