Converters

A converter is like an ordinary proc except that it enhances the “implicitly convertible” type relation (see Convertible relation):

# bad style ahead: Nim is not C.
converter toBool(x: int): bool = x != 0
if 4:
  echo "compiles"

A converter can also be explicitly invoked for improved readability. Note that implicit converter chaining is not supported: If there is a converter from type A to type B and from type B to type C the implicit conversion from A to C is not provided.
