I like the idea but I find the syntax (both suggestions) less than great, given
that there’s already “ensure a type” syntax, and both suggestions are already
used for other things (casting and foreach)
Is there some reason (eg ambiguities) a type can’t just be placed before a
variable to ensure a type, similar to a function parameter or typed property?
Eg
string $foo = 'bar';
array $bar = getBar();
foreach($bar as int $k => string $v) {...}
Cheers
