N/A

What did you do?

Moused over the type time.Duration

What did you see happen?

Type declaration, type documentation comment, type method set displayed.

What did you expect to see?

See a list of time package defined constants of type time.Duration as well as what is already provided. Probably not of all constants, 6 or so would be already helpful to get an idea of the type's use.

Thanks for the issue.

I'm not sure this would be universally useful. The way to find usage of a type is to find references, though in the case of time.Duration, that may be noisy.

It is important that hover information be succinct, and mixing in usage information seems counter to that goal.

Maybe it makes more sense for the special case of enum-like constants defined with = iota. So think of time.Weekday
