for each loop with condition

Compare:

for each(book in books where book.pages > 100) { do(); }

for each(book in books) { if(book.pages > 100) { do(); } }

Compare:


for each(book in books where book.pages > 100) { do(); }


for each(book in books) {
  if(book.pages > 100) { do(); }
}

That's more compact, but is it worth adding keywords (where) and
complexity when you can easily write:

for each (book in books) { if (100>book.pages) continue; do(); }
