Re: NEWBIE - generics issue

[LeuGim]

I get no compiler error for your example (maybe there is some problem in your 
full code), just a run-time error from dispatcher, because you didn't allocate 
the object for `a` (via `new`, as the variable is of reference (pointer) type, 
not object itself). The full code:
    
    
    type
      Something = object
        a: int
        special: Special
      
      Special = ref object {.inheritable.}
      SpecialisedTA = ref object of Special
        abc: string
      SpecialisedTB = ref object of Special
        def: string
    
    import json
    
    method foo(s: Special, node: JsonNode) {.base.} = assert(false, "Kinda 
abstract")
    method foo(s: SpecialisedTA, node: JsonNode) =
      s.abc = node["abc"].getStr()
    method foo(s: SpecialisedTB, node: JsonNode) =
      s.def = node["def"].getStr()
    
    var a = new SpecialisedTA
    var jsonNode = parseJSON"""{"abc": "5", "def": "7"}"""
    echo jsonNode
    foo(a, jsonNode)
    echo a.repr
    
    
    Run

Wrapping your code in posts with "```nim" and "```" makes it highlighted.
