## std.convert: Classes for type coersion and conversion.
## This module is imported by default.

## The Coerce class is used for type conversion that will not fail.
## Its associated methods, `from` and `into`, are used internally
## by the compiler for implicit type conversion (coersion).
pub type Coerce[T] = class
  to(Self): T
  # from(T): Self

## The `from` function is automatically implemented for all types that
## implement `to`: that is, all types T that are convertable to U.
pub func from[T: Coerce[U], U](self: U): T =
  to(self)

## The Convert class is used for type conversion that may fail.
# We'll see what this breaks.
pub type Convert[T, E] = class
  to(Self): Result[T, E]
