One case which string can be useful but a callable would not be acceptable is:
array_map([I18N::class, translate::function] );
I wouldn't expect that to work anyway, because the whole purpose of the
keyword would be to resolve "translate" as a function name, not a method
name, e.g.
use Acme\Global\I18N;
use function Acme\Global\translate;
var_dump([I18N::class, translate::function]);
# array(0 => 'Acme\Global\I18N', 1 => 'Acme\Global\translate')
# not a valid callable
var_dump([I18N::class, 'translate']);
# array(0 => 'Acme\Global\I18N', 1 => 'translate');
# this was what was intended
If you didn't want to quote the method, you'd need some other syntax
that took both class and method name, like:
[I18N, translate]::callable
Or as proposed elsewhere in the thread:
$(I18N::translate)
