Perhaps just the *perceived* emphasis is wrong? Let me elaborate...
My intent was only to indicate that I don't think we *gain* anything by
having two forms that are quite similar both syntactically and
semantically. Both [...] and list(...) use exactly the same syntax for
the inner expression. Both use parentheses/brackets, so the inner
expression can be broken across multiple lines in the same ways. Both
produce the same result, a list created in the appropriate manner.
So why have both? That's all I meant by TOOWTDI.
FWIW, I've posted my arguments for removing the redundant [...]
expression in Python 3.0 at:
 Reminder: I'm *not* arguing for list literals to look like
list(...), only for list comprehensions to look that way.
