new example:
for (<init>; <cond-a>; <incr>) {
if (<cond-b>) {
try { // is C++, but doesn't matter
<code-a>
if (<cond-c>) continue;
<code-b>
} catch(...) {
<code-c>
}
<code-d>
} else {
<code-e>
}
}
Python: ?
With some effort, one can surely craft equivalent code in Python,
but I bet it will become considerably longer, and likely you'll
have to repeat some of the code-blocks, or introduce new flag-variables.
point taken ?

Yes, it occurred to me already:
case=lambda x: my_special_compare(switchvar,x)
if case('blah'): ...
elif case(42): ...
elif case("foo") or case("bar"):
print "sufficiently near to a fallthrough :-)"
elif case(r"^(.*)foo(.*?)$"): ...
...
switch is indeed not needed in python.
