Instanceof feature for protocol's

[griffith1deady]

how do I know that my object can be converted to my interface via toProtocol, as languages usually implement instanceof?
and nice library, thanks for your hard work!

import oolib

type 
    TileEntity {.inheritable, protocoled.} = tuple
     sout: proc(data: string)

class MyTileEntity impl TileEntity:
    proc sout(data: string) = echo(data)

let myTile = MyTileEntity.new()
echo myTile is TileEntity #false

as my workaround about it:

import oolib

type 
    TileEntity {.inheritable, protocoled.} = tuple
     sout: proc(data: string)

class MyTileEntity impl TileEntity:
    proc sout(data: string) = echo(data)

proc `is`[T](val: T, dest: typedesc): bool =
    result = when compiles(val.toProtocol): getTypeInfo(typeof(val.toProtocol).default) == getTypeInfo(dest.default) else: false

let myTile = MyTileEntity.new()
echo myTile is TileEntity #true
echo myTile is string #false

There is no procedures like instanceof for now, but your idea is so good I will start to implement it soon. Also, thank you for using my library:D
