Feature #6224: Make variables in if/unless conditions available to conditional statements

I propose to make below code work

do_something(a) if a = condition

Above code should work exactly same as

if a = condition
do_something(a)
end

If there is a reason behind why the first case does not work, please let me know.

Thank you.

I'm pretty sure this is already being discussed but I can't remember in what thread/issue.

[gcao (Guoliang Cao)]

I found this issue created 3 years ago. Matz explained the reason behind.

[rosenfeld (Rodrigo Rosenfeld Rosas)]

Exactly. Actually I didn't know about 1141, but I've read about 4965 recently.

The reason behind has been explained in #1141. If someone want to change the rule, he need to understand the rational first, then should try persuade me.
