Typical usages:
```
p ary[1..] # drop the first element; identical to ary[1..-1]
(1..).each {|n|...} # iterate forever from 1; identical to 1.step{...}

Currently, parser.y includes core parser and Ripper parser obscurity.
In addition, *some* Ripper code uses the result of the core parser,
which make it difficult to separate the two parsers.
I want to simplify this, not by separating the two parsers, but by
making *all* Ripper actions follows the core parser actions.
In other words, all the core parser actions run always even in Ripper,
and after that, Ripper-specific actions run.
For tha sake, in principle, I want to put `/*% ripper: ... %*/` in the
end of actions.
Anyway, it is too dirty to put it within expressions, IMO.
