Maybe you are interested in the Cobra Programming Language
(<http://Cobra-Language.Com/>)? The main feature of Cobra is that it
is designed with a "no holy cows" attitude: if there is a feature that
makes sense, it is added. Period. No flamewars allowed. And so, while
other language communities engage in the umpteenth flamewar about
whether static or dynamic typing is better, Cobra simply has both.

Chuck Esterbrook (<http://CobraLang.BlogSpot.Com/>), the designer of
Cobra, has a very simple guiding principle: a programming language
should help a programmer to achieve her goals. And those goals are:
productivity and quality. There are a number of language features that
help with productivity (dynamic typing, implicit typing, expressive,
concise, lightweight syntax, high-level abstractions) and there are
features that help with quality (static typing, explicit typing,
language-integrated documentation, language-integrated testing, design
by contract). There are some languages that have all the features in
one list (Ruby, Python, Perl, Smalltalk, Lisp), some have all from the
other list (Eiffel, D), some have some from both lists (Objective-C,
Perl6 have static and dynamic typing, Haskell has static and implicit
typing plus expressive syntax and high-level abstractions). But none
have all of them. Well, until Cobra.

First two caveats: Cobra is a CLI language, and it is still in
development. However, Chuck Esterbrook has used Cobra commercially in
production systems for many years now.

Cobra achieves this by starting with the syntax of Python, but
massively cleaned up (no gratuitous self, no __underscores__, no
colons). Then you add the object model of C# and the contracts of
Spec#. Whenever there is a C# concept that cannot be expressed with
Pythonic syntax, steal from VB.NET. Add unit tests analogous to
contracts and docstrings. Throw in streams from C�, for good measure.
Make static typing the default, but implicit.

Well, you get the idea.
