Why on earth would you recommend this outdated hack, when there's a true
conditional operator?
To learn a bit about the interchangeability of control and data
structures?
[Just playing devil's advocate]
But it doesn't do the same thing.
Comparing:
x = cond ? f() : g(); # C version
with
x = [f(), g()] [cond]
the latter evaluates both f() and g() instead of just one. Apart from being
inefficient, it can have unintended side-effects.
