How to access variable by its name

Question

How can I access variable by its name?

a = Hash.new
a["test"] = 9
some_method(:a) # => {"test" => 9}

Does this help? `a = 7; binding.local_variable_get(:a) #=> 7` or `eval("a") #=> 7`. — Cary Swoveland, Jun 05 '15 at 01:55
There is a 99% probability this is an [XY problem](http://meta.stackexchange.com/questions/66377/what-is-the-xy-problem). What are you really trying to do? — Amadan, Jun 05 '15 at 02:00
