class SyntaxTree::YARV::OptArefWith

### Summary

‘opt_aref_with` is a specialization of the `opt_aref` instruction that occurs when the `[]` operator is used with a string argument known at compile time. There are fast paths if the receiver is a hash. It pops the receiver off the stack and pushes on the result.

### Usage

~~~ruby ‘test’ => true ~~~
