Re^3: Two simple code style advice questions

It probably means "Using '... x condition' is not always safe":

say $_ ? "true" : "false", "a" x $_ for 0, 1, "0e0";

Now what do you mean by that? What is it that you expect and how is it unsafe?

The issue is that the code relies on true being represented by numeric one. While that works for numeric comparisons, it is not a safe assumption in general. So applying this construct to other kinds of tests could be dangerous.
