If we call "var a:int", a is set to be 0. Then, are there any way to set to be call some proc like "default" immediately after "var" call? It seems that there is default proc for type int, string, float but these proc is not called after var call.
I know that we can make another macro "var2" to realize this purpose. I also know that calling "var a:seq[int]", a is set to be an empty seq and not nil. How is this done?
