Typically I see this happen when the function returns an array.  You're
seeing the number of variables in the returned array probably.  Try
@example.com = xxx()
and see what happens.

Perl detects scalar/list context and behaves differently and if you aren't
used to it, it can throw you.  For  instance $x = @example.com will assign 4 to x if
there are 4 elements in y, or $x = grep something, @example.com gets the number of
matches, not their values.
