is_map
(class=typing #args=1) True if argument is a map.
is_nan
(class=typing #args=1) True if the argument is the NaN (not-a-number) floating-point value. Note that NaN has the property that NaN != NaN, so you need 'is_nan(x)' rather than 'x == NaN'.
is_nonempty_map
(class=typing #args=1) True if argument is a map which is non-empty.
