} but I think it should be.  ;-)

The manual is woefully short of examples; it's almost exclusively limited
to descriptive text.

In any case, in 3.1.4 with the "stat" module loaded, you can do it with

    sumsizes() {
        local sum sizes i
	stat -A sizes +size $*
	sum=0; for i in $sizes; ((sum += i))
	print sum
    }

E.g.
	sumsizes **/*.o

Replace +size with +block if you want the actual disk block usage.

In 3.0, there's no direct way to read the size of the file into the shell.
You'd have to run "ls" and parse the output, or something.
