  # The checked form raises on overflow — which in this prelude is a panic,
  # since `__crystal_raise_overflow` prints and exits (SPEC.md III.1.4).
  #
  # The unchecked form is the conversion without the check, and a float
  # past the range saturates (NaN is 0), alike in every build. It is
  # spelled the way `unsafe_chr` below is: `unsafe_to_u8`. Crystal spells
  # it `to_u8!`, which is not a name in iyi (SPEC.md III.1.7) — those
  # declarations were accepted only because a macro expansion was
  # reparsed by the other language's rules, and no iyi source could call
  # one: `x.to_u8!` is `x.to_u8` with its error propagated. The callers
  # wanted the instruction: `memset`'s `value.to_u8!` is C's "converted to
  # unsigned char", and the checked form panics on 0x1ff where C writes 0xff.
