class SyntaxTree::YARV::ConcatArray

### Summary

‘concatarray` concatenates the two Arrays on top of the stack.

It coerces the two objects at the top of the stack into Arrays by calling ‘to_a` if necessary, and makes sure to `dup` the first Array if it was already an Array, to avoid mutating it when concatenating.

### Usage

~~~ruby

1, *2: ~~~
