a == b | Bool | Self equal to other by value: an Eq term, never a Python bool. |
a != b | Bool | Self not equal to other by value: a Ne term, never a Python bool. |
.is_empty() | Bool | True if this Form yields the EMPTY sentinel. |
.not_empty() | Bool | True if this Form does not yield EMPTY. |
.fallback(*alternatives) | Self | The first of this value and alternatives that is not EMPTY. |
