I am writing a lambda calculus in F#, but I am stuck on implementing the beta-reduction (substituting formal parameters with the actual parameters).
(lambda x.e)f
--> e[f/x]
example of usage:
(lambda n. n*2+3) 7
--> (n*2+3)[7/n]
--> 7*2+3
So I'd love to hear some suggestions in regards to how others might go about this. Any ideas would be greatly appreciated.
Thanks!
