confusion i have with comma operator.
docs seem to indicate it evaluates both sides, but i see examples where it
looks like if it evaluates to false on LHS it doesn't evaluate RHS. i see
this in examples of writing a case statement.
$x='b';
{
($x eq 'a') && (print 'a'), last;
print 'x';
}
i see it work sortof sometimes - if $x isn't equal 'a', 'last' isn't
evaulated and it prints 'x'.
shouldn't it also evaluate 'last', whether the LHS of that line is true or
not?
in fact, i just tried it again and this time it didn't work - it evaluated
'last' and didn't print anything.
