Doesn't work when you need to chain more than one method or even pass 
argument:

dates.select _.greater_than old_date
(dates.select &:"greater_than #{old_date}" not only doesn't work, but if 
did, it would take the current value of old_date, not the one you'd get 
when you evaluate the block)

But for the very most simple examples, you are right.
