What does that mean? Every program ultimately interfaces with its
environment and must do so in the correct way. When a program gets
this wrong then it has an error, and that is true even when the
program is written in Ada. This example proves that Ada programmers,
even ostensibly good ones who work for the company that makes the
compiler, can make "stupid" mistakes like putting in extra quotes
where they don't belong. That's a given, of course, because no one
is immune to this sort of error, but as I said, in these language
wars people erroneously progress from "my language is immune to a
certain class of errors" to "my language is immune to errors".
