(j3.2006) Can't figure out what this means

[Van Snyder]

In 7.2.3.1p2 we read


        "If a where-construct contains a where-stmt, a
        masked-elsewhere-stmt, or another where-construct then each
        mask-expr within the where-construct shall have the same shape."


To which where-construct does "the same shape" apply?  The outer one,
the inner one, or both?

>From the discussion of control masks in 7.2.3.2, it appears to be both.
If so, it would be clearer as "... then every mask-expr within the
entire where-construct, including mask-exprs within nested
where-constructs, shall have the same shape."



The confusion is caused by using "each" instead of "every". The phrase
"... then each mask-expr within the where-construct shall have the same
shape." makes one ask "same shape as what?"
