I tried to close the bug in the bugs database but my password doesn't seem
to work anymore. Any ideas? Where has the username field gone? :)

Only increment works with strings in PHP, decrement doesn't. When you
decrement a string it gets
converted to a long and is then decremented.
The reason is that like Perl, we didn't see much use for string
increment/decrement except for testing purposes and creating unqiue ideas
so increment should be enough.
