Element - λ - Lambda

Characters: λ


Create a lambda function (pushes an anomymous function to the stack). λarity|code; defines a lambda function with the given arity (if unspecified, the arity is 1). When a lambda is applied with (Function Call), it pops that many values from the stack and places them on its own stack in reverse order. Then, the function body is run with that sub-stack. Finally, if the function's stack is non-empty, its top value is pushed back onto the stack. Otherwise, the original top-of-stack is pushed back.
