So, you're not surprised that this Om page has an extensive section called "Examples", right? https://www.om-language.com/#language__examples__

One time, this annoyed me so much that I made a website.

https://anaminus.github.io/langding/

om would fall under "Yes, must scroll".

There is code. Small examples start halfway down the page, and there's one 20-line example. Not much, but it's not accurate to say there's none.

It would be helpful to see any kind of motivation for the project though. Anything at all.

There is code, search for 'examples'.

It concludes by implementing a fold:

   define
   {
       [Fold]<- {
           rearrange
           {
               rearrange
               {
                   dequote
                   choose
                   quote Result
                   pair pair pair {[Fold]<-} Function Result Remainder
                   Remainder
               }
               {Result Remainder}
               dequote Function Base <-[terms] Source
           }
           {Function Base Source}
        }
   }
   {
       [Fold]<- {[literal]<-} {} {1 2 3}
   }
