$binding global var?

Ruby

Hello,

Can anyone satisfy my curiosity and tell me what the global variable
$binding is for?

I though it might be a default binding for eval calls but my tests didnt
concur.

my ruby and irb don’t know about $binding, it’s not in the pickaxe and
not in the quickref - where did you encounter it?

Irb uses $binding. But ruby does not:

$ ruby -ve ‘p global_variables.grep(/binding/)’
