Related problem

Say I have the following:

# A fancy function that does something.
export def foo [
    bar: string = "bar" # Some parameter description.
] {
    print $bar
}

If I run help foo, the following is displayed:

➜ help foo
A fancy function that does something.

Usage:
  > foo (bar) 

Flags:
  -h, --help - Display the help message for this command

Parameters:
  (optional) bar <string>: Some parameter description.

Describe the solution you'd like

It would be very useful for default parameter values to also be mentioned when using help, since then I know when I can safely omit the parameter :)
