This seems to be the treatment of that symptom. > Has "add named placeholders to *printf()" been proposed/discussed before (I didn't find)? What about strtr() (e.g. `strtr('The {foo} is {bar}.', ['{foo}' => FOO, '{bar}' => bar()])`)? (and even templating engines like Twig?) Anyway, it sometimes baffles me indeed that I can build a string with a method call like "...{$foo->bar()}..." but not with a function call like "...{foo($bar)}...", and also with complex interpolation via callable variable like "...{$foo($bar + baz($qux))}..." but not with simple constant like "...{FOO}..." or operation like "...{$foo + 1}..." :/ Regards, -- Guilliam Xavier
