Would it make sense to show the hidden values from the stack in the debugger?

This would show in the case of message sends with parameters the actual parameters that will be used.

For example below [temp2] and [temp3] are the two parameters of #openInWindowLabeled:inWorld, 

while [temp1] is the receiver.

The downside is that in methods with loops this will also show the internal index of those loops.

Cheers,
