It's true only in a numeric context.
When used as strings, uninitialized variables are automatically
initialized to an empty string.
Although this peculiarity is emphasised throughout the rest of the manual,
I think it would be useful to mention about it in the introduction
chapter too (especially for novices).

Thanks for the note. Looking at the section as a whole, I think it
would be distracting to try to introduce information about initialization
to the empty string.  Sometimes it's better not to be fully complete.

So, I appreciate your making the suggestion, but I think it better to
leave that section alone.

Or just a minimal cosmetic change: "initialized to null value" instead of "initialized to zero".

Just my 2c.
