I agree with Barry. In particular, the behaviour of adding spaces
between items is something I find very useful, and it's missing from
the functional forms.

    print greeting, name

feels much more natural to me than

    write(greeting, " ", name)
    writef("%s %s", greeting, name)

And that's even worse if the original used a literal "Hello", and only
later migrated to a variable greeting - remembering to get the spaces
in the right place is a pain:

    print "Hello", name  ==> print greeting, name
    write("Hello ", name) ==> write(greeting, name) # oops, forgot the space
or                               write(greeting, " ", name) #
non-obvious translation

OK, it's a minor thing, but what's the benefit?

I've used print functions a lot in things like VBScript and
Javascript, and hated them every time...
