... implementing the "Elvis operator" ... as $x ? $x : $y

Actually, I read the opposite from the Wiki article:

... the Elvis operator expression A ?: B is approximately equivalent to the ternary conditional expression A ? A : B

... something like ... x = f() ?: g() ... is equivalent to ... the conditional ternary operator x = f() ? f() : g() except that it does not evaluate f() twice if it yields truthy.

Accentuations by me.
