If I pass lazy expressions or delegates to as arguments to functions, what

mistakes here?
If anyone can comment on how these features are implemented in generated code
wrt stack-allocated objects that
are _in_ lexical scope in a delegate evaluation context, then I'd be interested
to hear about this.
They all local variables (or similar) that a delegate references will be
allocated on the heap, this is also known as a closure:
