Well, than say it to Joe :-)

'and' is and in mathematical manner
'andalso' is lazy and in programmers manner

I think there is no way to change it, because if you remove 'andalso' and
use 'and' in programmers manner lazy behaviour, you will break some legacy
code a vice versa. This change is impossible. You can be not agree with it.
You can argue against it, but it is all what you can do with it.
