Golang: The prompt information of the function and the prompt information of the parameter conflict

[wanglong001]

It even obscures what is typed

It can be done a little more humane：
When entering parameters, you can remove the prompt information of the function,
When you enter comma, the function prompt information will come out again

This can be better to use, hope to improve this user experience

This is because there's no space above. We display one above and one below if possible
