Not so pragmatic, Dave! ;)

Speeding up gargbage collection is an important issue, but:
The mark/sweep technique is linear in the allocated memory, therefore:
Reducing the number of allocations clearly speeds up the garbage 
collection. This could be a main issue after optimizing the collection
itself. I think therefore, that my idea on the operators could speed 
up a lot.

I don't think, that static typing information in Ruby script is only
"a particular path". 

It has a lot of facets: code clearence,effectivnes, genericity,
optimazibility,programming philosophy... I think, it is a most 
serious issue. However, the later does it happen the harder will it
be.

Please, think about it!
