If temp vars dot matter, then Ned and Lex have provided examples. Also, you can use something like: 

 
Compiler evaluate: '[myInstanceVar class] value' for: self logged: false

If you intend for the block's code to access temporary variables declared in the method that created it, Workspace and Debugger provide two different approaches.
