Hi!
I think there's definitely the start of a good idea here, but the syntax you
suggest doesn't read quite right. As has been pointed out, this differs from
existing features in two ways:
- the special handling is for any non-iterable value, not just null or
empty/falsey values, for which you could use $foo??[] and $foo?:[] respectively
- the handling is to skip the loop, not loop once assigning $bar to the scalar
value, as would happen with (array)$foo
The challenge, then, is to come up with some syntax that somehow suggests these
rules. The "??" is too much like the null coalesce, which would be misleading.
The only idea that immediately comes to mind is a keyword:
foreach ifarray ($foo as $bar) {
I can't say I'm that keen on that syntax, but maybe it will inspire someone
else.
