[Haskell-cafe] Very silly

Not that I want or need to defend C++ on this list, but 
reference-counted smart pointers (e.g. boost::shared_ptr<>), embedded 
inside copy-on-write proxy classes, largely simulates eager garbage 
collection. Targeted overriding of the new operator can make this lazier 
for efficiency.

In other words, there are well established idioms in most successful 
languages to solve obvious problems. Haskell's strengths are more in 
making these idioms simple and robust enough for the average user, not 
just the guru, and to make difficult or impossible the misuse of unsafe
