Nim: [Generics] Can't infer generic params via a constructor

Created on 20 Jul 2019  路  2Comments  路  Source: nim-lang/Nim 
type Foo[T] = object
  a: T

var 
  bar = Foo[int](a: 1) # okay
  baz = Foo(a: 2)      # Error: object constructor needs an object type

Generic procs already have some inference capability, why not constructors?

Because nobody ever implemented this feature. Features start in the unfortunate state "Unimplemented".
