What about "%%%(x)s%%" % locals()

Nope it does not ;)
Adding magic handling of strings would make another wart in a clean and 
elegant language.

Not really. Python already has:
1.) print >>f, data
2.) "format" % data

If you do not want exact formating the first one is quite acceptable:
>>> import cStringIO
>>> x=cStringIO.StringIO()
>>> print >>x, "Hello World."
>>> x.getvalue()
'Hello World.\n'

Try Ruby. It's got more perlish features.
