Since we already have some backward-incompatible changes this 
time, I'm inclined to agree the time is right for

OR:  "|" -> "||"
AND: "&" -> "&&"

If we do this I'll make an effort to provide what Sven very 
reasonably requested some time back, namely good error messages in 
case "|" or "&" seem to be used in their old sense, with a 
"redirect" to the currently accepted syntax, e.g.

 for AND, please use "&&"
