* array.c (rb_ary_sample): improve performance when many samples
from a large array. based on the patch by tomoya ishida
<tomoyapenguin AT gmail.com> in [ruby-dev:49956]. [Bug #13136]
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57380 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
The current documentation for Array#join does not mention the
special treatment of nested arrays.
It says:
> Returns a string created by converting each element of the
> array to a string, separated by the given separator.
Expected behavior according to the docs would be:
[ "a", [1, 2, [:x, :y]], "b" ].join("-") #=> "a-[1, 2, [:x, :y]]-b"
# because of:
[1, 2, [:x, :y]].to_s #=> "[1, 2, [:x, :y]]"
Actual behavior:
[ "a", [1, 2, [:x, :y]], "b" ].join("-") #=> "a-1-2-x-y-b"
because join is applied recursively for nested arrays.
The patch clarifies this behavior.
(Also: small markup and grammar fix.)

Shrinking the Array from the block invoked by Array#select! or
Array#reject! causes the Array to be a negative number size. Ensure that
the resulting Array won't be smaller than 0.

Since the Array may be modified during rb_yield(), the length before
invoking the block can't be trusted. Fix possible out-of-bounds read in
Array#combination and Array#repeated_combination.
It may better to make a defensive copy of the Array, but for now let's
follow what Array#permutation does. [ruby-core:78738] [Bug #13052]

The sentence `Negative values of +index+ count from the end of the array.` can be interpreted that it only holds if a block is given. Clarify it.

* array.c (rb_ary_and): clarify that set intersection returns the
unique elements common to both arrays.
* array.c (rb_ary_or): clarify that union preserves the order from
the given arrays.
- Most know what intersection means, but saying the operation
excludes duplicates could be misleading ([1] & [1], duplicates
excluded, might mean a result of []).
- Instead, saying intersection returns the unique elements common to both
arrays is more concise and less ambiguous.
- The set union's documentation was incomplete in its describing
preservation of order. Saying union preserves the order of the
original array neglects the idea that the order of the elements
in both arrays, as given, will be preserved.
- Instead, saying set union preserves the order from the given arrays (and
adding an example) fully demonstrates the idea.
