No, that's not okay.  However, Ruby allows statement modifiers, so we  
can reverse that:

do_this() if condition?

That is allow and no end is needed.

The above is fine.  You can also replace then with it's symbol  
shortcut, in recent versions of Ruby:

if condition? : do_this() end

No braces for if's, use end instead.

Hope that helps.
