Your reasons for doing this are somwhat bogus -- in perl6, one of the new operators (that you're ignoring in the table, so it's reasonable to overlook them) is a boolification operator, so you don't have to abuse !. Simply write ?$expr == ?$cond. Also, you could define a new operator, say infix:ile (for Is Logicly Equivlent To): 

sub infix:ile is tighter(==) {
 ?$^a == ?$^b
}

(This uses theDamien's placeholder vars, which I'm not sure are in exactly as I've used them. I need to find time to read A6 again, more carefuly. Also, it may be possible to write this as... 
sub infix:ile($a is bool, $b is bool) is tigheter(==) {
 $a == $b
}

And rely on the compiler to coerce the arguments to bools.)
