Poll: Python-style ternary operator (was: Syntax polls)

[pitao]

Python-style ternary operator: a if pred else b

Arguments in favour:

• It does not have to be learned. A nonprogrammer can parse it.
• syntax highlighting will split a and b very nicely, as the keywords will be a different colour.
• it reads naturally. (i.e. it conforms to our natural language). ‘Pythonic’.

Arguments against:

• people are familiar with ?:
• ?: is fewer characters

My preference would be to have both available. When concision is paramount, use ?: otherwise use _ if _ else _.

• pred ? a : b ftw.
• a if pred else b wins, kill ?
• Allow both!
• MOO
