I've never used this construct myself, and tt does seem unintuitive and contrary to perlsynL: "The "while" statement executes the block as long as the expression is true (does not evaluate to the null string "" or 0 or "0"). ".

FYI, the output of deparse (which gets it wrong, occasionally) is: 

> perl  -MO=Deparse -e 'while () { print "..\n" }'
while (1) {
    print "..\n";
}
-e syntax OK
