/* The default implementation of #=== is
* to call #== with the rb_equal() optimization. */
/*!
* This function is an optimized version of calling #==.
* It checks equality between two objects by first doing a fast
* identity check using using C's == (same as BasicObject#equal?).
* If that check fails, it calls #== dynamically.
* This optimization actually affects semantics,
* because when #== returns false for the same object obj,
* rb_equal(obj, obj) would still return true.
* This happens for Float::NAN, where Float::NAN == Float::NAN
* is false, but rb_equal(Float::NAN, Float::NAN) is true.
