Hmm – I forgot Python has `else` for `for` and `while` too. But it's a tad
difficult to wrap one's mind around the meaning of the word `else` in this
particular context whereas it actually means `nobreak`. Perhaps if this were
added to D, `default` would be a better choice of keyword, since we all know
that `default` (as in `switch`) is not executed if `break` happens.
So:
try { code_which_can_throw(); }
catch { handler(); }
default { only_if_didnt_throw(); }
finally { mandatory(); }
How does that look?
