That "casein" next to "switch" bugs me. Did I already propose:
switch: local_sabbath()
case (1, 2, 3) as sabbath:
...
case 6:
...
else:
...
The key is to look at precedents:
try:
...
except (E1, E2) as e:
...
except ...:
...
finally:
...
and:
lambda: expression
The "switch: day" format is a hybrid of the "try" and "lambda" syntaxes
and would be compatible with existing Python editors as well as general
Python sensibilities.
