What is YARV?

Ruby

I see it’s a VM for Ruby, but what does that mean and what is it good
for?

Here’s a poster from last year that may help explain what it’s all
about:

Put shortly, it’s a Rubyists (for given values of Rubyist, notably
including
me) biggest dream. If it works out, Ruby scripts will run Damn Fast
compared
to how they do now. They could also be distributable in a compact
wordcode
form, for all the good and bad that brings.

i also silently hope for YARV to run / compile in a mode without support for string-based eval, the mild deprecation of that horrible, completely unoptimizable language feature in the core / stdlib in favour of the multitude of much cleaner reflection and metaprogramming present in Ruby, so that there's at least a remote hope of such wonders like clean blocks that don't prevent their entire scope from being GCed just because the interpreter can't tell whether it will be used. Etc.
