Possible workarounds for subclassing a c++ class and overriding a virtual method

[krakengore]

That's a clever trick, thank you! It still require i have a c++ class tho, not 
sure if i can have an imported c++ class as {.inheritable.} with a virtual 
method and inherit from it in a nim object of and use the exportcpp trick to 
override the virtual method (because at that point it is a nim object and not a 
c++ sublass anymore)
