why not to call the section 'Running code in the default state' and the
method just `.default_context()`:
with context_vars.default_context():
# here, all context vars start off with their default values
# here, the state is back to what it was before the with block.
Means `clean` here `default` (the variable is constructed as
cvar = ontextvars.Var(default="the default value", ...) ?
Thanks in advance,
