For example:

type loglvl int

type LoggerPlugin struct { 
  Config struct {
    Level loglvl `name:"log" type:"counter" short:"v" help:"Log level. Higher = more verbose." default:"0"`
  } `embed:""`
}

Results in:
panic: reflect.Set: value of type int is not assignable to type cmds.loglvl

Removing the counter type, or setting the type back to int works fine.

Is there any way we could add support for counters with custom types as shown in the above example?
