complete. Although the intent is to develop it into a full-featured language, the software is currently at a very early "proof of concept" stage, requiring the addition of many operations (such as basic number and file operations) and optimizations before it can be considered useful for any real-world purpose. It has been made available in order to demonstrate the underlying concepts and welcome others to get involved in early development."

    define { minutes { dequote choose {minutes} {} = {:} <-[characters] } } { minutes {1:23} }

    "1:23".split(":", 1)[1]

    def minutes(x): 
        return x[1:] if x[0] == ':' else minutes(x[1:])
    minutes("1:23")

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

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

om would fall under "Yes, must scroll".

I see what you did there with the parentheses.
