Webb8 dec. 2024 · Tail call optimisation (or TCO) is a fascinating optimisation technique that is commonly discussed in the functional programming community, because of it’s importance in the implementation of efficient recursive algorithms. However, it is often overlooked when discussing other programming languages. Webb18 aug. 2010 · 9. Although modern compilers MAY do tail-call optimization if you turn on optimizations, your debug builds will probably run without it so that you can get stack traces and step in/out of code and wonderful things like that.
