Is it a secret?
I'm a little perplexed at why you say a language without "elif" is a good
sign of brain-death in a programming language. I understand that, given
the parsing rules of Python, it is better to use elif than the equivalent:
if condition:
pass
else:
if another_condition:
pass
But that's specific to the syntax of the language. You could, if you
choose, design a language where elif was unnecessary:
if condition:
pass
else if another_condition:
pass
What advantage is there to "elif", apart from it needing three fewer
characters to type?
