Infer ExtensionDtype based on object #27995
Description
Would it be possible to infer ExtensionDtypes based on the objects inside a list/array that are used to construct a series?
Eg with an array of pint's Quantity objects:
>>> array_of_qty array([<Quantity(67.0, 'meter')>, <Quantity(61.0, 'meter')>, <Quantity(30.0, 'meter')>, ..., <Quantity(293.0, 'meter')>, <Quantity(886.0, 'meter')>, <Quantity(165.0, 'meter')>], dtype=object)Could pandas infer the dtype as PintType in this command?:
df.elevation = array_of_qty
