The primary purpose of this is to wrap the double-underscore methods of `~astropy.units.Quantity` which is the superclass of `~astropy.constants.Constant`. In particular this wraps the operator overloads such as `__add__` to prevent their use with constants such as ``e`` from being used in expressions without specifying a system. The wrapper checks to see if the constant is listed (by name) in ``Constant._has_incompatible_units``, a set of those constants that are defined in different systems of units are physically incompatible. It also performs this check on each `Constant` if it hasn't already been performed (the check is deferred until the `Constant` is actually used in an expression to speed up import times, among other reasons). c^d}hd}ttD][\}}t|tjr<|dr'|dr||vr||||<\t ||||S)NcFtjfd}|S)Nc |j}|j|}|jsh|D]L} |j|j##t$r|j |YIwxYwd|_|j sK||jvrBtd|D}td|j d|j d|dd|g|Ri|S)NTc3K|]}||V dSN).0xs :lib/python3.11/site-packages/astropy/constants/constant.py zFConstantMeta.__new__..wrap..wrapper..0s'$?$?1Q$?Q$?$?$?$?$?$?

These objects are quantities that are meant to represent physical constants. Parameters ---------- abbrev : str A typical ASCII text abbreviation of the constant, generally the same as the Python variable used for this constant. name : str Full constant name. value : numbers.Real Constant value. Note that this should be a bare number, not a |Quantity|. unit : str String representation of the constant units. uncertainty : numbers.Real Absolute uncertainty in constant value. Note that this should be a bare number, not a |Quantity|. reference : str, optional Reference where the value is taken from. system : str System of units in which the constant is defined. This can be `None` when the constant's units can be directly converted between systems.
