----------------------------------------
Feature #4257: switch_hitter - an acceleration of date library
http://redmine.ruby-lang.org/issues/4257

Author: tadayoshi funaba
Status: Closed
Priority: Low
Assignee: tadayoshi funaba
Category: ext
Target version: 


 switch_hitter'ed already passed nearly all of tests (except some tests
 of class name and some confirmations of format of inspect).
 
 * The constructors may return Date::Light instead of Date.
 * as fast as home_run when it represents simple date of proleptic
   gregorian of the age of the human race.
 * keeps compatibility.
   - can load ruby 1.9.2 dumped marshal.
 * accepts flonum explicitly with limitations.
   - If the given offset is flonum, DateTime assumes its precision is
     at most second.
   - If the given +/- argument is flonum, DateTime assumes its
     precision is at most nanosecond.
 
 I'd like to apply this to trunk in the near future.
 I also have a plan of improvement about some format methods.
