Linear

Convenience class to indicate the variable of an expression's linear term when iterating over the expression's components.

Note that the bias corresponding to this variable is not part of this class.

Examples:

>>> from luna_quantum import Constant, Expression, HigherOrder, Linear, Quadratic
>>> expr: Expression = ...
>>> vars: Constant | Linear | Quadratic | HigherOrder
>>> bias: float
>>> for vars, bias in expr.items():
>>> match vars:
>>>     case Constant(): do_something_with_constant(bias)
>>>     case Linear(x): do_something_with_linear_var(x, bias)
>>>     case Quadratic(x, y): do_something_with_quadratic_vars(x, y, bias)
>>>     case HigherOrder(ho): do_something_with_higher_order_vars(ho, bias)
