Intolerable is a strong word. I've yet to have a problem with this, because
it almost never goes wrong in real life (maybe during a code/test iteration,
but it's not problematic at run-time). Typo's only slip through if you
do a wrong assignment (e.g. "Foo = 1" and "foo = 2"). In an OO system, 
variables typically have a very limited scope, are qualified by classnames
and therefore tend to be shorter, largely alleviating the problem procedural
languages have with undeclared variables.

Could you elaborate? It seems quite open to me. Even the GNU project
accepts Java software, nowadays.

Depends what you define as a) "a type", and b) "type checking" for Python. It
also assumes that an absense of whatever you define under b) is a
disadvantage, but there are more languages that employ the same kind of
type checking (Smalltalk, to name one) and are quite succesful. It's
different, but it works.

But it'll always stay a write-only language.
