[Pharo-users] RB refactoring rewrite variable to a symbol

Hi, how can I rewrite a(n instance) variable to a symbol? E.g. [IN] something: aSomething something := aSomething [OUT] something: aSomething self write: aSomething into: #something I can capute the input just fine... ``@var := ``@arg but I have no idea how to convert the var into a symbol (or string). Thanks, Peter
