Dynamically set local variables in Ruby [duplicate]

Question

This question already has answers here:

How to dynamically create a local variable? (4 answers)

Closed 4 years ago.

I'm interested in dynamically setting local variables in Ruby. Not creating methods, constants, or instance variables.

So something like:

args[:a] = 1
args.each_pair do |k,v|
  Object.make_instance_var k,v
end
puts a
> 1

I want locally variables specifically because the method in question lives in a model and I dont want to pollute the global or object space.
