Subject: Calling a block with parameters in a new scope

Calling a block in a new scope is easy enough:

self.instance_eval &block

And calling a block, passing it parameters is easy enough:

block.call(*params)

But is there some way to do both? To both change the scope of evaluation 
and pass variables into the block.
