Hi Midori,

Forgive my rookieness and let me introduce my first RFC here:
https://wiki.php.net/rfc/null_coalesce_equal_operator
<https://wiki.php.net/rfc/null_coalesce_equal_operator>
I think this is a reasonable proposal. I had foreseen that we might add
a ??= operator some day when I wrote the original RFC for the ?? operator.
I do have one thing to add, though. It's something of a nitpick, but the
name ought to be the "null-coalescing assignment operator". This would
follow the convention of referring to +=, -= etc. as compound/combined
assignment operators[1][2], not "equal" operators (which sounds more
like what == and === do, to me) and avoids the mistake ("coalesce"
instead of "coalescing") that I originally made in my RFC for ??.[3] I
think that RFC naming is important, because the name the author chooses
for a feature tends to be the one that ends up in the manual.
Anyway, thank you for your RFC!
