Subject: [ruby-core:71662] [Ruby trunk - Feature #11734] Improved ternary	operator

Issue #11734 has been updated by Daniel P. Clark.


`&` is associated more with proc.  I think `_` would be closer to the kind of thing you're looking for.

~~~ruby
some_long_expression = :baz
_ ? _.to_s : 'foobar'
# => "baz"
~~~

Although I tried in-lining it with a semicolon and found that the `_` feature only works off of the previous' lines results. So the following won't work.

~~~ruby
:baz; _ ? _.to_s : 'foobar'
# => "foobar"
~~~

And this doesn't work

~~~ruby
x = 4
:fiz ? _.to_s : 'foobar'
# => "4"
~~~

So if you don't mind putting your ternary operation on the next line you can just use `_`

----------------------------------------
In ternary operator it would be nice to be able to pass expression result from *condition*  into *value_if_true/value_if_false* in such way:

`some_long_expression ? &.to_s : 'foobar'`
where `&` refers to `some_long_expression`

Instead of doing:
`some_long_expression ? some_long_expression.to_s : 'foobar'`

or:
`result = some_very_very_long_expression
result ? result.to_s : 'foobar'`
