In this particular case, there would be no problem, because $raise
would be "consumed" by the "%s" in the initial string and would not
be evaluated for format descriptions. There is a problem, however;
if a variable contains a percent sign and is not consumed by a
preceding format description, it could confuse printx. Hmmmm.
I like being able to simply include variables and strings, letting
them auto-convert (as in print). OTOH, my proposal has some holes
(as you note) and may not be easy to error-check.
The C# syntax looks interesting. I suspect that some variant of it
could be dropped into Perl as a module, so it wouldn't break anything.
Here's another approach, FWIW:
print
f('The value of $foo is %f7.3; ', $foo),
f('the value of $bar is %f7.3.%n', $bar);
print
f('The values of $foo and $bar are %f7.3 and %f7.3, ', $foo, $bar),
'but the value of $baz ', f('is %f7.3%n', $baz);
This assumes that the first argument to "f" is a format description
and the other values are its arguments. Careful reader will note that
"f" is basically sprintf.
