Description Usage Arguments Functions Examples
Where cases
evaluates expressions based on pattern matches,
this function creates a long ifelse expression that tests patterns in turn
and evaluate the expression for a matching pattern. This function is intended
for metaprogramming rather than usual pattern matching.
1 2 3  cases_expr_(expr, ...)
cases_expr(expr, ...)

expr 
The expression to test against. This is usually a bare symbol. 
... 
Pattern matching rules as in 
cases_expr_
: Version that expects expr
to be quoted.
cases_expr
: Version that quotes expr
itself.
1 2 3 4 5 6 7 8 9 10  linked_list := NIL  CONS(car, cdr : linked_list)
length_body < cases_expr(
lst,
NIL > acc,
CONS(car, cdr) > ll_length(cdr, acc + 1))
length_body
ll_length < rlang::new_function(alist(lst=, acc = 0), length_body)
ll_length(CONS(1, CONS(2, CONS(3, CONS(4, NIL)))))
