How to strip() all instance var of class instance?

Rails
1

Something like x.instance_variables.each… { |i} … }

Ought to be a one liner. I can’t figure out how to apply strip() to each
variable, since instance_variable_get returns the value. I really want
something I can apply .strip! to…

What make you think you can’t do that to the result from
instance_variable_get ?

You are correct - this works. But, why? Doesn’t instance_variable_get return
the value of a variable, not the actual variable itself?

instance_variable_get(:@foo) evaluates exactly the same object as @foo.
