Which is not that different from Ada - only in Ada it tend to be a "don't do
the check" compiler option or pragma statement.

Thats because high cost has a different meaning in Ada. There is that
famous:

pragma suppress(numeric_error, horizontal_veloc_bias);

which has cost ESA � 860.000.000.

Of corse they would have found that bug if the ESA management had decided to
rerun the test suite before employing old software on a new rocked.
