I was just pointing out that the problem of finding meaningful 
identifier names is wider in scope than the naming of function objects.

Surely the "cout" in parenthases following "write" gives a clear hint at 
the destination of the write.

Having said that, the statement I posted was:

for_each(c.begin(), c.end(), write(cout));

But you seem to have removed the salient part in your quote.
