Yes.

How would you handle translatable user visible strings - such as
"Parsing '${file_name}' failed on line ${line_number}." (where "${...}"
identifies parameter substitutions) - in Ada?

The standard library is definitely not (intended to be) the tool for
that job.

Two of the challenges are:

 + How can we (at compile-time) check that the named parameters in the
   translatable string match the parameters passed to the formatting
   routine?

 + How can we (at load-time) check that the parameters used in a
   translated string match those in the translatable string?
