What can qualify for potential tail call recursion (TCO) optimization or tail recursion elimination (TRE)
Short question is: what can qualify for potential tail call recursion optimization (TCO) or tail recursion elimination (TRE) if the compiler or interpreter supports it.
The summary of this question ...

Different Implemenations of Tail Call Optimisation
I've heard some people in my university discuss the tail call optimisation in ML as if it were a special version tail call optimisation.
Does the ML (SML/F#) implementations of tco in these languages ...

General recursion to tail-recursion
Is it theoretically possible to transform every kind of general-recursion into tail-recursion? Are they equivalent for example from a lambda-calculus point of view? That's a debate between me and an ...

Continuations, coroutines, and tail-call optimization
I am trying to learn continuations and use them to implement coroutines in Scheme.
I have two procedures (coroutines) a and b, and I switch between them in the following way:
;; c is a continuation.

When there's no TCO, when to worry about blowing the stack?
Every single time there's a discussion about a new programming language targetting the JVM, there are inevitably people saying things like:
"The JVM doesn't support tail-call optimization, so I ...

Tips for Tail Call Recursion in Python [duplicate]
Ok, Python doesn't have tail call optimization.
But for those who think better recursively than "looply", whats the best practices to write code??
1000 stack calls are enough for many cases, but ...

Which are the alternatives to using a stack to represent function call semantics?
We all know and love that function calls are usually implemented using the stack; there are frames, return addresses, parameters, the whole lot.
However, the stack is an implementation detail: ...

Y combinator and tail call optimizations
The definition of a Y combinator in F# is
let rec y f x = f (y f) x
f expects to have as a first argument some continuation for the recursive subproblems.
Using the y f as a continuation, we see ...

What limitations does the JVM impose on tail-call optimization
Clojure does not perform tail call optimization on its own: when you have a tail recursive function and you want to have it optimized, you have to use the special form recur. Similarly, if you have ...
