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,
