Subject: [ruby-core:61654] [ruby-trunk - Feature #9667] Optimization of	__FILE__ and __dir__

Issue #9667 has been updated by Tsuyoshi Sawada.


Sorry, my examples were inappropriate. Please ignore the examples above.
<hr>
Currently, different object id is returned each time:

    2.times{puts __FILE__.object_id}
    # => 70183725179420
    # => 70183725129020

I propose them to be optimized so that they are only created once per occurrence.

    2.times{puts __FILE__.object_id}
    # => 70183725179420
    # => 70183725179420

In the same spirit as the string literal followed by `freeze` is optimized, I think `__FILE__` and `__dir__` should be optimized. Currently, they return different object id each time they are called.

    __FILE__.object_id # => 70183725179420
    __FILE__.object_id # => 70183725129020
    ...

I propose them to be optimized so that they are only created once per occurrence.

    __FILE__.object_id # => 70183725179420
    __FILE__.object_id # => 70183725179420
    ...
