Description
Bug report
Summary
Arithmetic on Decimal values crashes the interpreter if the decimal_context context variable has been set to something that isn't a decimal.Context.
Expected: a TypeError when the variable does not hold a Context.

import decimal
decimal.getcontext()
var = next(v for v in contextvars.copy_context() if v.name == "decimal_context")
