Issue #21365 has been updated by fxn (Xavier Noria). `instance_eval` modifies the nesting in the eval'ed code. Since namespaces are modules, `instance_eval` already works: ```ruby ns = Namespace.new ns.instance_eval "p Module.nesting" ``` That prints `[Namespace]`. I believe @tenderlove's wants a regular top-level execution context, where the nesting would be empty, in particular (mod https://bugs.ruby-lang.org/issues/21318). ---------------------------------------- Feature #21365: Add `Namespace#eval` https://bugs.ruby-lang.org/issues/21365#change-113441 * Author: tenderlovemaking (Aaron Patterson) * Status: Open ---------------------------------------- I would like a way to eval code on to a `Namespace` object. Could we add an eval method that _doesn't_ take a binding object? Writing a new file every time I want to test Namespaces is too cumbersome. Thanks! -- https://bugs.ruby-lang.org/
