A brief snippet:

"My company is about to start development on a new project, and I have 
to decide on a language and development environment. My boss gave me a set 
of criteria which needs to be filled: intuitive and easy to use IDE; 
simplified GUI design and event handling; advanced error handling; 
advanced object oriented design including multiple inheritance, abstract 
classes, and garbage collection; full support for operator and function 
overloading; and portable (at compile-time) across various platforms. I 
have already looked at C++, Java, C++, C#, Eiffel, and even VB.net; I may 
be missing something but as far as I can tell all of these languages are 
missing something from this list. Is there a language available that has 
all of these features? I thought that someone from Slashdot would be able 
to point me in the right direction?" If you were to design a language from 
the ground up, what features would you include and why?"

Looks to me as though Squeak has most (all?) of what this guy's looking 
for? Any Comments?
