	Mark array as "going to be modified" in `Array#reject!`

	Before this patch, if `reject!` is called on a shared array it can
	mutate the shared array rather than a copy.  This patch marks the array
	as "going to be modified" so that the shared source array isn't
	mutated.

	[Bug #15479] [ruby-core:90781]

Improve Array#- efficiency [Fixes GH-1756]

2017-12-19T01:08:52+00:00

When doing the difference of a small array with a big one it is not
efficient in both time and memory to convert the second one to a hash.
