I understand your idea.  However, the difference between a statement
and a function is exactly my point, and I see it as relevant--if any
language change is to come from this discussion.  New functions can be
added via modules, and do not require changes to the language itself.
New statements require changes to the language itself, which is what
the OP is asking for.  

The [in]ability to define "custom shortcuts", with regards to
statements, is especially relevant because Python doesn't support it.
Other languages do (Ruby?  et al), so someone thinks it's relevant.
It's relevant because if Python *did* support it, this thread wouldn't
be happening.  (Or at least would have ended after someone 
replied with "oh, just do XYZZY to make a printraw statement".)

I'm not trying to be pedantic (at least, I think I'm not trying), but
the difference between a statement and a function is a semantic
difference, not (just) a syntactic one.

The logic is that "much the same" is not "the same", and is the point
of the OP's plea.

In any case, I think the one-liner posted satisfies nearly all of the
requirements.  

import sys
def pr(*args): sys.stdout.write(''.join([str(i) for i in args]))

Where it fails is the difference between a function and a statement.
The OP said [one of] the advantages of a statement is that there is no
need for parenthesis.  This is the reason I brought up the point that
a function and a statement are semantically different, and why none of
the function-based suggestions will satisfy the OP's plea.
