class SyntaxTree::YARV::GetBlockParamProxy

### Summary

‘getblockparamproxy` is almost the same as `getblockparam` except that it pushes a proxy object onto the stack instead of the actual value of the block local. This is used when a method is being called on the block local.

### Usage

~~~ruby def foo(&block)

block.call

end ~~~
