In every programming language I've ever heard of, program control flows left→right and then top→bottom. That is, this psudo code:

{ print "1" } { print "a" }
{ print "2" } { print "b" }
{ print "3" } { print "c" }

would print 1a2b3c

Are there any languages (even eso-langs/DSLs) that invert that order, so that the above would print 123abc?

It occurs to me that a left-to-right control flow would be a good fit for a lot of "pipeline" type data work, and I'm curious if anyone has tried it

@codesections There is the apl "family" of languages that go from right to left.
@codesections Just see this -> https://www.youtube.com/watch?v=_DTpQ4Kk2wA
In apl, data flows through procedures from right to left.

Some esolangs have 2d execution flow if you're interested.

Also, if your comment that

> APL is an underrated gem

wasn't a reference to the classic comparison between Lisp and APL, it really should have been!

> APL is like a beautiful diamond – flawless, beautifully symmetrical. But you can't add anything to it. If you try to glue on another diamond, you don't get a bigger diamond. Lisp is like a ball of mud. Add more and it's still a ball of mud – it still looks like Lisp.
