No, I don't.
If I'm writing in C, and I want to know whether one of my variables is
"empty", I have to know what type of variable it is. The code to check
whether a string (char x[10]) is "empty" is very different from the code
to check whether an array of integers (int x[10]) is "empty". Hell,
the meaning of "empty" would have to be defined by the application.
Would it mean every element is 0? Or something else? And what if x is
a float, or a double? Or a pointer? Or a struct?
The same thing happens in bash. It's simply not the kind of language
where you have one syntax that works for multiple situations.
