One less-than-pleasant method of knowing whether a parmaeter is
going to be changed by a function call is to name the function
appropriately.  e.g.

	getName(string);

versus
	setName(string);

From their names, the latter would probably not change the value
of "string".

Basically, I agree with you.  I miss being able to look at code
and know immediately whether or not a parameter would be modified
by that wonderfule marker, "&".
