support

Can anyone tell me if there are any clients (browsers) that define a functioning Object.prototype.hasOwnProperty that do NOT define a Function.prototype.call?

That is, must I use belt and suspenders to qualify clients for a certain level of scripting, or will hasOwnProperty do for both?

if(Object.hasOwnProperty && Function.call){
// add script
}

Is support for either of these properties a reliable subset of support for the other?
