scheme - How do I return a copy of an object? -
i need implement function of 1 argument -- obj
-- returns scheme expression that, when evaluated, return copy of obj
.
any ideas on how proceed problem?
i'm guessing meant write "a function expr-returning [that accepts an] obj [and] returns scheme expression that, when evaluated, ..."
assuming case: need here design recipe. begin with: write down examples of function accepts, , returns. clarify you're trying do, both others , (probably more importantly) yourself.
hope helpful; sorry opaque...
