As an escape continuation, more than you'd expect. (Exception handlers, early return.) Full continuations are rarer, but I use them for doing error recovery.

Aw, no call-with-current-continuation?

What tmtvl said is correct. However, it is also a resource problem. R7RS Large is a volunteer driven effort where if people stop having the time to contribute due to personal reasons, things slow down. > If it's the latter, is there

We plan to add delimited continuations in a later draft. What the actual API will look like is still in question. There is a proposal for a large API, like Racket's < https://srfi.schemers.org/srfi-226/ > and

Hello everyone. Working Group 2 is pleased to announce the first draft of the second part of the R7RS-Large Foundations, the "Procedural Fascicle". This draft encompasses the familiar block programming forms, such as lambda, let,

> FL HOTDOG.MIAMI.FL.US. arodriguez@houseit.com I'm very confused by this entry. There isn't even a miami subdomain, just a Dade subdomain.

If you want to peer into an alternative reality / funhouse mirror of programming terms, you should look at ALGOL 68. For instance, types are called "modes". https://jemarch.net/a68-jargon/ (There are als

Would SectorLISP ( https://justine.lol/sectorlisp2/ ) count? It can run the LISP 1.5 metacircular evaluator.

From John Cowan: TAGBODY doesn't actually require continuations, delimited or undelimited, just proper tail calling. A macro can rewrite each section of the TAGBODY into a procedure nested within a `let` that tail-calls its successor

I guess I'll have to read more about effect handling systems, I'm very much out of my element there. > yes, macros are hygienic! I'm glad. Too many lisps chicken out and don't add them. > easier to type! Fair enoug

As someone who writes a lot of Scheme, I agree that the math syntax is not good. There have been proposals to add infix expressions ( https://srfi.schemers.org/srfi-105/ ) but nobody seems to want them, or can agree on s

1. I don't know much about HM systems mathematically, but how do the effect handlers interact with type inference? I thought there was some issues with automatic inference there. 2. The macros examples on the website don't show bi
