Nim's equivalent of kwargs

[4n0n4me]

I don't think there is kwargs in Nim. It may be possible to implement similar 
things with macros. You can also just do
    
    
    import std/tables
    
    proc foo(a: int, b: string, kwds: seq[(string, string)] = @[]) =
      let kwdTable = kwds.toTable
      echo kwds, kwdTable
    
    foo(1, "bar")
    foo(2, "baz", @{"kwarg1": "value1"})
    
    
    Run

Nim is a static typed language and functions must have certain parameters known 
at compile time. (btw, in Nim it is relatively hard to do dynamic types, 
compared to modern C++ `std::any`, Go `interface{}` and Rust `std::Any`, Nim 
doesn't have such things widely used or in standard lib)

Disclaimer: I am not very familiar with Nim, so maybe I am wrong.
